Abstract

By exploiting the high contrast in the optical properties of the phase change material Ge2Sb2Te5 between its amorphous and its crystalline stable phases (ncryst−namor=2.5 and kcryst−kamor=1 at 1.55 μm) [1] a thin film (20 nm) of this material deposited on top of a microring resonator can be used to modify its losses and effective refractive index, thus changing the position and shape of the resonances in the transmission spectrum.
