Ge2Sb2Se4Te on Insulator: A Tunable Monolithic Platform for Integrated Photonics with Large Thermo-optic Coefficient
We demonstrate a tunable monolithic platform using Ge 2 Sb 2 Se 4 Te on insulator for integrated photonics. The platform features a thermo-optic coefficient of 3 . 228 × 10 −4 ± 1 . 879 × 10 −6 K −1 , and allows post-fabrication phase tuning via laser-induced crystallization.
