This paper demonstrates the design, construction, and performance of a monolithically integrated wavelength-division-multiplexed transmitter module having ten distributed-Bragg-reflector (DBR) laser diodes operating at predefined frequencies in the 0.98μm to 1.0μm range with a frequency separation of about 2nm. The DBR gratings are written by focused ion beam lithography with manual stepping of the x-deflection gain to produce the required variation of period.
