Talks & Events

The Rochester Section meets approximately twice each month, usually on Tuesdays. Our meetings include a talk by a featured speaker. Each talk is preceded by an informal dinner at a local restaurant with the invited speaker. The annual dinner meeting in May includes a banquet dinner. These meetings are open to all individuals.

    Chip-based beam-steering with optical phased arrays (OPA) and lens-assisted beam steering (LABS)

    Steven Spector, Draper Laboratory

    Beam-steering is an important component in LiDAR and free space optical communication (FSOC) systems. Large mechanical systems for beam-steering provide good optical performance, but are undesirable for many applications due to their size, cost, and complexity. Two chip-based beam-steering solutions, optical phased arrays (OPA) and lens-assisted beam steering (LABS), will be discussed. In an OPA, an array of coherent beams are combined, and the relative phase of the beams is controlled to allow steering of the net beam. This is common technique in RADAR systems, but only recently has it become feasible in an optical system. In a LABS system, a lens is used to create a beam, and the direction of the beam depends on the emission (or receiving) location of the light in the focal plane of the lens.

    About the speaker

    Dr. Steven Spector is a Distinguished Member of the Technical Staff and Group Leader at Draper, where he is leading efforts in integrated photonics, imaging and LiDAR. He received a B.S.E. in Engineering Physics from Lehigh University in 1991, and a Ph.D. degree in Physics from the State University of New York at Stony Brook (now, Stony Brook University) in 1997. Prior to joining Draper, Steve worked at Lincoln Laboratory from 1999 to 2015, where he lead silicon photonics efforts and was also responsible for a number of projects in nanofabrication. Prior to working at Lincoln Laboratory, Steve was a post-doctoral fellow at Bell Laboratories, developing EUV lithography.

    Optical fusion splicing for integrated photonics chips

    Juniyali Nauriyal, Photonect Interconnect Solutions


    With the increasing need for higher data rates of the order of a few terabytes to zettabytes, data centers and optical transceivers companies are now migrating to integrated photonics to keep up with the data rates. However, packaging of integrated photonic devices to optical fibers remains a slow and expensive process. To keep up with the highly data-driven communication systems and with the advent of co-packaged optics, a low-cost and low-loss packaging technique that can be scaled to high volume manufacturing for photonic integrated circuits is needed. We present a packaging technique that uses fusion splicing to connect optical fibers to integrated photonics chips.

    About the speaker

    Juniyali Nauriyal is a co-founder of Photonect Interconnect Solutions Inc and a Ph.D. student at the University of Rochester. She is working on packaging integrated photonic devices by providing a high-performance and cost-effective solution. She is a Ph.D. student of the Electrical engineering Department at the University of Rochester. She completed her B.E. degree from Mumbai University in India in 2016 and got her MS degree from the Institute of Optics at the University of Rochester in 2018. She was awarded the Harvey M. Pollicove Memorial Scholarship in 2018 by OSA (Optical Society of America Foundation), she was also awarded the Best ISA Student Award in 2016 by ISA-Maharashtra (International Society of Automation).

    Photonic Smart Coatings for the Enhancement of Photovoltaic Power Generation

    Dr. Nishikant (Nish) Sonwalker, SunDensity


    The photon management on a glass substrate (SiO2) has attracted significant interest in the opto-electronic industry. The one-dimension photonic crystals show significant promise for the photon capture for optoelectronic applications. The periodic dielectric layers of the transparent nano-layers can form a one-dimensional photonic crystal in the form of Bragg reflector. The properties of Bragg reflection are well-known and studied extensively in optoelectronic applications, such as DBR and VCSEL laser and fiber optic applications. We have designed and developed plasmonic interface to the Bragg reflectors with metal nano particles for the coupling of plasmonic energy to the photon transfer through resonant nano-cavities and Bragg reflectors. The effect is to manage the photon wavelengths in the region of interest while harvesting the several low energy photons using photonic crystal layers for creating a photonic smart coating for PV cells.

    The broader impact of Photonic Smart Coating (PSC) will be to significantly improve the power output of photovoltaic solar cells and sensors to accelerate generation of clean power. This photonic spectrum shaping technology can be applied in numerous industries including Solar Panels, Optics, Imaging, and Display devices generating large number of high paying hi-tech jobs across USA.

    Dr. Sonwalkar will present the concept of photonic smart coatings, founding of SunDensity and his journey from Boston to Rochester for manufacturing scale-up and growth.

    About the speaker

    Inventor, academician and musician Dr. Nish is a pioneer in the field of solar energy technology. He is actively involved with the research and development related to advanced photonics and nanomaterials for solar applications. His inventions related to photonics and nanomaterials motivated him to create SunDensity’s Photonic Smart Coating Technology, which has the potential to revolutionize the solar energy industry. As the research faculty at MIT, he developed the combined molecular dynamics (MD) and laser Raman spectroscopy methodology for the design of photonic coatings and material interfaces. He has also served as PI on numerous NSF research and SBIR awards related to surface sciences and education technology. He received Doctor of Science degree from the Massachusetts Institute of Technology.
