DFB Waveguide All-Optical Switching Devices Employing Pump-Induced Refractive Index Change in GaInAsP
A pump-induced refractive index change was measured in a passive GaInAsP waveguide together with its temporal response. Also, the temporal response of distributed feedback (DFB) waveguide transmittance modulated by the pump-induced index change was experimentally investigated for an application to all-optical switching devices.
