Switching Characteristics of All-Optical Wavelength-Selective Switch Using Waveguide-Type Raman Amplifiers and 3-dB Couplers

摘要

Switching characteristics such as wavelength dependency and phase dependency are investigated for our proposed switch which consists of waveguide-type Raman amplifiers and 3-dB couplers. As a result, the available range of wavelength and phase shift due to nonlinear effect are estimated about ±20 nm around 1.55μm and about ±10 degrees, respectively.
