The performance of random-wavelength switching of a wavelength-tunable three-electrode DBR laser is demonstrated. Packet header information is used to randomly switch the currents of the laser and route 155 Mbit/s data packets onto four different wavelength modes. BERs of 10/sup -9/ are achieved over a 4.8 nm tuning range with a packet guard time <25 ns and a packet holding time >3 mu s. Mode-partition...
