A Fast 100-Channel Wavelength Tunable Transmitter for Optical Packet Switching
01 July 2001
We demonstrate a fast wavelength tunable transmitter, based on a widely tunable GCSR laser diode for optical packet switching application. A high-speed control driver board is built to facilitate the fast wavelength channel selection and control. It supports 100 wavelength channels spaced by 0.4 nm with SMSR > 30 dB. Wavelength switching is in nanosecond range and its characteristics have been studied.
