Controlled switching of phase-change materials by evanescent-field coupling in integrated photonics

Abstract:

Fully controllable phase-change materials embedded in integrated photonic circuits are a promising platform for on-chip reconfigurable devices. Successful experimental demonstrations have thus far enabled non-volatile multilevel memories and switches, optical synapses, and on-chip photonic computing. However, the origin and mechanism behind the phase switching has not been described in detail. In this paper, we study qualitatively the evanescent field coupling between Ge2Sb2Te5 and the confin...
