Photonic Integration for RF Photonics Systems Photonic integration on the Silicon Photonics platform, together with heterogeneous integration to include other materials, provides an ideal platform for the development of complex photonic integrated circuit (PIC) devices. This talk will describe the requirements for basic RF Photonics systems, including low noise lasers, linear modulators, low loss optical processing elements, and high power photodetectors, followed by descriptions of devices and PICs that Morton Photonics is developing for these functions.
The talk will describe how a high performance PIC including arrays of these devices can be utilized for the processing of a phased array sensor to provide Multiple-Channel Simultaneous RF Beamforming, and describe potential commercial markets for these technologies, including automotive LIDAR systems, analog photonic links and RF Beamforming for 5G systems

Fluency Lighting Technologies is an early stage start-up company developing technology out of UC Santa Barbara. At Fluency, we are creating next-generation bright and narrow-beam light sources for highly efficient illumination, using laser technology and materials design. Our focus is the development of low-cost, optical platforms that convert laser diode emission into high-quality white light in various light levels, beam angles, and color temperatures, designed for customer-driven metrics, in applications where energy-saving LED technology is not used because of the limited light output from an LED.

In recent years, widely tunable micro-electro-mechanical systems vertical cavity surface-emitting lasers (MEMS-VCSELs) have found commercial application in swept source optical coherence tomography medical imaging and also show considerable promise in metrology and spectroscopy. These devices exhibit fractional tuning ranges of >11% of the center wavelength, wavelength tuning repetition rates over full tuning range of >1MHz, and clean single-mode operation. These properties, in conjunction with small size and wafer scale fabrication and testing, promise an economical optical source that can impact sensing applications from the visible to the mid-infrared.

Chris will discuss next-generation optical interfaces for large scale datacenters, including Intensity Modulated Direct Detection and Coherent technologies at 100, 200, 400 and 800 Gb/s rates. He will show several examples of how applying insights gained from previously successful applications can lead to flawed conclusions about different applications. If he is persuasive, students will no longer trust what they are taught by their professors and other experts.

Today zettabytes of data are generated and nearly doubled every two years. The conventional microprocessor is reaching its physical limitation and cannot keep up with the exponential growth in rich data. This leads to the increased demands on memory systems due to their frequent access patterns between microprocessors and memories. High speed, low energy and high sensitive optical data links are desirable for data transmission between multicores, microprocessors and memories in the new data center and high performance computer architectures. I am going to talk about the silicon photonics efforts in developing low energy high speed optical links in Hewlett Packard Labs, including the development of low voltage SiGe avalanche photodiodes, as well as photonic links.

The continuing growth in demand for bandwidth (from residential and business users), necessitates significant research into new advanced technologies that will be employed in future broadband communication systems. Two specific technologies, becoming increasingly important for future photonic systems, are wavelength tunable lasers and optical frequency combs. Although these topics have been studied for over two decades their significance for the development of future ultra-high capacity photonic systems has only recently been fully understood. Wavelength tunable lasers are currently becoming the norm in optical communication systems because of their flexibility and ability to work on any wavelength. However, as their operating principles are different to standard single mode lasers they can effect how future systems will operate. For example as optical transmission systems move towards more coherent transmission (where the data is carried using both the intensity and phase of the optical carrier), the phase noise in these tunable lasers will become increasingly important. Optical frequency combs also have many applications for future photonics systems, and for telecommunications they can be used to obtain the highest spectral efficiency in optical transmission systems by employing the technology of optical frequency division multiplexing (OFDM), and also for generation of high frequency RF signals in future 5G networks. Wavelength tunable lasers and optical frequency combs are thus topics at the leading edge of current photonics systems research, and their detailed understanding promises new applications in all-optical signal processing, optical sensing and metrology, and specifically telecommunications. This talk will focus on the development and characterization of various wavelength tunable lasers and optical frequency combs, and then outline how these sources can be employed for developing optical transmission systems and networks which make the best use of available optical spectrum.

Abstract: In this presentation, Garrett provides an overview of how two scientists from the University of Vienna stumbled upon an enabling technology, born from fundamental research in the burgeoning field of cavity optomechanics, and made a successful transition from academia to industry. The fruit of this endeavor is “Crystalline Mirror Solutons,” or CMS, a photonics start-up commercializing high-performance optics for laser-based precision measurement and manufacturing systems. Here, Garrett outlines the key elements that led to their successes, including the conception of the underlying technology, as well as the supporting infrastructure and funding organizations that ultiately assisted in bringing this idea out of the laboratory and onto the
Bio: Dr. Garrett D. Cole, Co-Founder of Crystalline Mirror Solutions (www.crystallinemirrors.com), obtained his PhD in Materials from the University of California, Santa Barbara in 2005. Since completing his doctorate, he has held positions ranging from the first employee of a high-tech startup (Aerius Photonics LLC, now FLIR Electro-Optical Components), to a postdoctoral position at Lawrence Livermore National Laboratory, a Marie Curie Fellow of the Austrian Academy of Sciences, and, prior to leaving to found CMS, an assistant professor in the Faculty of Physics at the University of Vienna. In the course of his research career, Dr. Cole has co-authored 2 book chapters and published more than 50 journal articles and conference proceedings including papers in Science, Nature, Physical Review Letters, and the Proceedings of the National Academy of Sciences. Leveraging his expertise in micro- and nanofabrication, tunable lasers, and cavity optomechanics, Dr. Cole developed the proprietary substrate-transfer process at the heart of Crystalline Mirror Solutions and, along with Professor Markus Aspelmeyer, co-founded the venture in February 2012.
Abstract: Success in a photonic startup company requires constant attention to the balance between risk and opportunity. These risk / opportunity decisions involve many different areas, technical, marketing, financial, organizational and psychological, among others. Some of these decisions are very specific to photonic startup issues but the balance of opportunity and risk touches on a broad range of aspects of life, of course.
This presentation discussed the general nature of risk and opportunity and from these general ideas will then derive recommendations for effective risk management methods in photonic startups. The presenter did this through examples drawn from his own experience and from the experience of others that have influenced him strongly
