Abstract :
In this paper, new technologies will be described to develop WDM laser diodes (LD)s at a reasonable cost by simultaneous fabrication of multiwavelength lasers on a chip or on a wafer. The necessary pitch corrugation formation for DFB or DBR semiconductor lasers on the same wafer has been successfully demonstrated by applying new and precise computer-controlled electron beam (EB) lithography
