A surface ridge DBR laser has been fabricated using conventional InP processing techniques, with the Bragg gratings defined by e-beam lithography. For a phase grating comb spacing of 6.8 nm, a nine grating device is predicted to yield complete coverage over >45 nm, sufficient to cover C- or L-band.
