High-density wavelength switching obtained from a tunable multisection laser diode.
We describe a method based on multistability in wavelength for obtaining high-density wavelength switching for application to signal routing. The method relies on the use of a 1550-nm wavelength-tunable multielectrode laser diode that is fed back electrically. The system operates as a multistable device that exhibits multiple steady states in wavelength. The device can be used to convert time-multiplexed packets into wavelength-multiplexed signals.
