Abstract

In this talk, I 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. I will also talk about different heaters that are needed to actuate the phase transitions on-chip. Specifically, I will show how using ultrathin graphene as a heater element can provide very high energy-efficiency, close to the fundamental limit set by thermodynamics.
