Abstract
Equivalent-chirp technology is demonstrated to enable fabrication of flat-top-envelop comb gratings with conventional two-beam-interference lithography, instead of e-beam. Widely-tunable DBR semiconductor lasers using such gratings are studied numerically, showing excellent uniformity and SMSR during tuning.
