Integrated Photonics (PI)

Integrated Photonics

The field of integrated optics is rapidly advancing due to the recent development in semiconductor and dielectric manufacturing which has enabled the miniaturization of both optical and optoelectronic devices. This group aims at explorations of new material platforms, novel nanofabrication techniques, integrated optical components as well as the development of large-scale photonic circuits with advanced functionalities for applications including optical communications, spectroscopy, laser ranging, optical computing, and quantum information. We also provide content (e.g. panel discussions, webinars, and social media) on current research trends in areas such as optical frequency combs, topological photonics, quantum photonics, microwave photonics. One of the most important goals of this group is to encourage and stimulate interactions between academic research and industry R&D on integrated optics, enabling innovation and fostering technology and product development.

Chip-Based Frequency Combs

When: 19 January 2021, 13:00 - 14:00 Eastern Time

Register Now

Applications based on optical frequency combs have rapidly grown in diverse areas of science and engineering, including chemical sensing, timekeeping, distance ranging, searching for exoplanets and as a source for wavelength-division multiplexing in data communications. Recent work has shown that chip-based nonlinear photonics offers the prospect of realizing comb devices in highly compact, portable, robust and fully integrated form factors that could make their use ubiquitous for a broad range of environments. Join the OSA Integrated Photonics Technical Group for a webinar with Alexander Gaeta, Columbia University, describing recent work on Kerr-comb generation and supercontinuum generation for producing broadband optical frequency combs in chip-based photonic platforms.
