Optical Switching of GeTe Phase Change Materials for High-Frequency Applications
Résumé
We present the optical switching of the GeTe
phase change material between its insulated and conductive
states using short (~ 30 ns) single UV laser pulses. The material
was integrated in high-frequency switches which can be optically
toggled between their ON and OFF-states in a bi-stable manner
on large frequency bands, up to 67 GHz.
