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. Bio: Eric Stanton attended Cal Poly San Luis Obispo, where he developed CubeSat nanosatellites and graduated with a B.Sc. in Electrical Engineering in 2012. During the summer of 2012 he worked at Agilent (now Keysight) before entering the graduate program at the University of California Santa Barbara (UCSB). In Professor John Bowers’ group, he developed integrated photonic technologies for a wide range of wavelengths from the visible to the mid-infrared. He obtained his Ph.D. in 2018 from the Electrical and Computer Engineering department at UCSB, and was awarded an NRC Postdoctoral Fellowship at the National Institute of Standards and Technology (NIST) in Boulder, CO. There he worked on nonlinear photonics and heterogeneously integrated lasers on silicon. Since 2020, he has been a CU Boulder PREP scientist at NIST. In 2021, he co-founded EMode Photonix, a photonics technology development company with the mission to make advanced photonic design tools more accessible.
 On Friday, May 27 at 5pm, graduate students, UCSB professors, and representatives from 10 local photonics companies gathered for a night of food and networking at the UCSB Corwin Pavilion. The Banquet began with a recruitment pitch for the Photonics Society followed by talks from Thorlabs, Nexus Photonics, and Raytheon Vision Systems who are all major sponsors of the Photonics Society this year. Thanks to their generous support, the photonics society was able to host this event and many other small events at no cost to attendees. After a bountiful dinner, Professor Bowers co-hosted a talk with all of the companies in attendance to provide an overview of all the photonics opportunities in Santa Barbara. The presentation slides from Thorlabs, Nexus Photonics, Raytheon Vision Systems, and Professor Bowers can be accessed here. In his talk, Bowers showed work from Quintessent, OpenLight (prev. Aurrion), Morton Photonics, OE Solutions, Aeluma, Freedom Photonics, Ultra-Low Loss Technologies, Mirios, and Nexus Photonics. During his talk he passed the microphone to several of the industry members from these companies, giving them a chance to talk about their work. Industry members were excited to be back in person for networking and several were actively hiring students at the event. Thanks again to our Sponsors and Parent Organizations!Learn more about our sponsors by viewing their presentation slides.

Think small: developing color centers in crystals for nanoscale optical sensors of fields and forces4/7/2019
 Friday, April 12 | 12:00pm | Elings 1605 From mapping inter-cellular mechanical interactions in the immune system to imaging magnetic phenomena in condensed matter systems, there is a growing need for noninvasive sensors with high spatial resolution. Color centers in crystals such as alkaline-earth upconverting nanoparticles (UCNPs) and the nitrogenvacancy (NV) center in diamond are an exciting class of sensors for highresolution imaging because of their optical readout, nanoscale size, and robust hosts. The first part of this talk will discuss UCNPs for mechanical force sensing in biological applications. UCNPs consist of a ceramic host doped with lanthanides (Yb3+ and Er3+). They operate by absorbing low energy infrared photons and emitting higher energy visible photons. Mechanical forces cause a change in the crystal symmetry and spacing of the dopant atoms, which results in a change of emission intensity and color. We have recently detected 27 nN forces with our UCNPs, a requisite for detecting inter-cellular forces in the immune system. The second half of this talk will discuss using the NV center in diamond as a magnetic force sensor. Through careful materials science studies in the Jayich lab, we created NV ensembles approaching the NV dipolar interaction limit of sensitivity. Using these NV ensembles, we imaged magnetic structure in CoTiSb. Refreshments provided!  Dr. McLellan explains that the up-conversion wavelength of nanoparticles depends on the pressure exerted. This effect allows the particles to be used as nano-scale forces sensors.
