 Friday, August 11th at 1:00pm in Henley Hall Semiconductor nanostructures with low dimensionality like quantum dots are one the best attractive solutions for achieving high performance photonic devices. When one or more spatial dimensions of the nanocrystal approach the de Broglie wavelength, nanoscale size effects create a spatial quantization of carriers. When directly grown on silicon, they even show a four-wave mixing efficiency much superior compared to the conventional quantum well devices. This remarkable result paves the way for achieving high-efficiency frequency comb generation from a photonic chip. Quantum dot lasers are a good candidate for applications in optical routing and optical atomic clock and quantum information processing. This lecture will review the recent findings and prospects on nanostructure based light emitters made with quantum-dot technology and their applications.

February 23, 2023 at 9:00 am in Henley Hall 1010 and on Zoom  Schematic diagram of optical waveguides with multiple longitudinal discontinuities (i − 1) [12]. The first discontinuity is located at z = 0. {ψ −}i and {ψ +}i are the backward and forward propagating fields, respectively, usually used in BiBPMs. Afaf Said, Khaled S. R. Atia, and S. S. A. Obayya, "On modeling of plasmonic devices: overview," J. Opt. Soc. Am. B 37, A163-A174 (2020) Nanophotonics modelling for 21st century applications is becoming vital. The computational modeling provides a fundamental understanding of the relying physics behind the operation of photonic devices. However, computational modeling is still a challenge as some of the existing modeling techniques fail to capture the correct behavior of nano-photonic devices. In this regard, this talk will introduce an overview of the existing computational modeling tools for analyzing photonic devices, in general, and highlighting their salient features and shortcomings. It is well known that “plasmonics” plays a vital role now in localising the optical field beyond the diffraction limit and hence in integrated optics. Therefore, the talk will focus on plasmonics modeling issues and the failure of the classical electromagnetic solvers to accurately characterize the nano-plasmonic devices. Therefore, new accurate and stable beam propagation method will be introduced for analyzing plasmonics in the classical regime. The rigor of this approach is mainly because of relying on the finite elements method and the twice faster Blocked Schur algorithm which can exactly represent all the wide spectrum of radiation, evanescent, and surface modes produced by the strong discontinuity between metal and its surroundings. Moreover, in merging quantum plasmonic devices, it becomes essential to introduce “Quantum Corrected Model (QCM)” in order to accurately model these devices, and the basics of QCM will be also discussed.

Friday, Jan 27, 1:00 pm (PST) in-person in Henley 1010  From Ref [4]: Spatial patterns in a monolithic ring laser comb. (a) Schematic of a ring cavity laser. (b) Intensity spectra of a ring QCL. Bloch gain leads to a multimode instability through phase turbulence [25]. A sech 2 envelope is fitted to the spectrum. Elimination of Bloch gain yields single-mode operation. (c) Temporal evolution of the intensity shows an initial turbulent regime that forms a frequency comb after 510 000 round trips. Optical frequency combs (OFCs) – whose spectra consist of a large number of equidistant modes – stand as the cornerstone of modern optics with applications ranging from fundamental science to sensing and spectroscopy. In this pursuit, semiconductor lasers have recently gained vast attention as an electrically-driven platform for self-starting OFCs, without the need for any additional components that are necessary for standard mode-locked lasers. Here, we explain the multitude of mechanisms that arise from fast gain dynamics of these lasers leading to rich nonlinear behavior. We first concentrate on the free-running combs in Fabry-Perot resonators, which are characterized by a linear frequency chirp and a continuous-wave intensity. We reveal the conditions for the formation of these frequency-modulated (FM) combs along with the optimization techniques that increase their spectral bandwidth [1,2]. Alternatively, ring resonators support unidirectional fields, where the multimode regime occurs only in the presence of the parametric gain, allowing the sidebands to overcome the lasing threshold [3]. We show that sensitive interplay between the dispersion and resonant Kerr nonlinearity [4] leads to the emission of OFCs and the formation of localized patterns in the laser output – ultimately enabling soliton generation.

Friday November 4th at 1:00 pm in ESB 2001 Coherent optical technologies enable high-bandwidth communication across the globe and are fundamental to the fiber optic backbone of the internet. Due to exponential increase in demand for bandwidth, and the subsequent rise of hyperscale data centers, coherent systems are now being used for shorter links, such as between data centers, or even inside of them. In this talk, I will first briefly review trends and the evolution of coherent optical modems, highlighting Ciena’s technology and contributions. I will discuss various challenges and solutions for next-generation coherent modems used in traditional medium-haul and long-haul links. In the second part of the talk, I will discuss the transition of coherent technologies to inter- and intra-data center optical links, focusing on data center switching bottlenecks, such as frontplate density, rack power consumption, and PIC shoreline density. I’ll then briefly review the use of optical frequency combs as a potential enabling technology for future data center links. In the final part of the talk, I’ll shift gears to professional development and give a brief overview of my experience with the Stanford Optical Society, balancing priorities during grad school, and the transition to industry.

Abstract: As photonics matures beyond component-based devices, complex photonic integrated circuits are now being developed to meet commercial needs at the forefront of technology. Performance metrics are continually improved for lasers, modulators, multiplexers, detectors, and other important photonic components, but one capacity that has historically been challenging to scale is the optical wavelength. To develop a fully functional passive and active platform for wavelengths across the visible to near-IR brings additional challenges introduced by the various fabrication constraints of the different materials integrated on the same substrate. In this presentation Eric will discuss recent work on highly efficient nonlinear waveguides and on-going research to integrate a visible laser onto silicon chips with wide-band frequency conversion resonators. Next, he will motivate the need for improved performance of photonics to meet the demanding requirements for integrated quantum optics. Finally, a new application of nonlinear optics in the far-UVC for disinfection and Raman spectroscopy will be introduced.

Thursday, June 23rd, 2:00 pm (PDT) -- Burgers from Kyle’s! Hosted in-person in Henley Hall 1010 Abstract – III-V compound semiconductor nanowires (NWs) have drawn much attention as nanoscale building blocks for integrated photonics/optoelectronics due to their nanoscale size, excellent optical properties and effectiveness in strain relaxation enabling the monolithic growth on lattice-mismatched substrates. In particular, NWs grown by selective area epitaxy technique have many advantages such as controllability of their size and position, high uniformity in diameter and length, as well as complementary metal-oxide-semiconductor (CMOS) process compatibility, facilitating their integration with other electronic devices. With suitable wavelength ranging from 1.3 to 1.6 μm and lattice match of constituent materials, InGaAs/InP quantum well (QW) has been being widely used for optical communication devices. However there has been limited understanding on the growth of InGaAs/InP QW in nanowire architecture and their application for optoelectronic devices such as lasers/LEDs and photodetectors. In this work, we present the study of the selective area epitaxy growth of InGaAs/InP multi-QW NW array by metalorganic chemical vapour deposition (MOCVD) technique, and the demonstration of nanowire LEDs/lasers and photodetectors with an investigation of their strong geometry related device properties by both numerical simulation and optoelectronic characterizations.

Friday, May 13th, 1:00 pm (PST) -- pizza provided! Hosted in-person in ESB 1001 and via Zoom Bio – Alexa Hudnut is an Optical Systems Engineer at Illumina in San Diego. Her research background is true to a Biomedical Engineer – a little bit of everything. She started her research in molecular biology and gene editing and then worked her way to instrumentation design and optics. She graduated with a PhD in Biomedical Engineering from the University of Southern California in 2018. She is most passionate about creating medical devices that leverage Optics and Materials Science for an intentionally sustainable future. Abstract – Illumina’s mission is to improve human health by unlocking the power of the genome. This translates to efforts such as tracking COVID variants, determining your dog’s breed, population genomics, and everything in between. Next generation sequencing (NGS) relies heavily on epifluorescence microscopy as the backbone of instrumentation. As we look toward the future of gene sequencing, it will become more prevalent as an in vitro diagnostic (IVD). To improve the clinical workflow, increased throughput is necessary for quicker turnaround times. These improvements are being driven by innovations such as structured illumination, multiplexing, image processing, and nanofabrication.
