Nonvolatile Electro-Optically Programmable Gate Array for Optical Interconnects

Eastern Time (US & Canada) (UTC -05:00)Large-scale, electronically reconfigurable photonic integrated circuits (PICs) can enable programmable gate array (PGA) to realize extremely fast, arbitrary linear operations, with potential applications in classical and quantum optical information technology. The basic building blocks of existing PGAs are thermally tunable broadband Mach-Zehnder-Interferometers, which pose several limitations in terms of size, power, and scalability. Phase change materials (PCMs), exhibiting large nonvolatile change in the refractive index, can potentially transform these devices, providing at least one order of magnitude reduction in the device size, zero static energy consumption, and minimal cross-talk.
In this webinar hosted by the Optics in Digital Systems Technical Group, Arka Majumdar will discuss different PCMs that can be used in conjunction with silicon and silicon nitride photonics, to create reconfigurable optical switches for visible and infrared wavelengths. Dr. Majumdar will also talk about different heaters that are needed to actuate the phase transitions on-chip.
