10 Lambda Monolithic Selectable Source On Inp Integrating A Dbr Laser Array And A Phasar

A 10 lambda selectable source, with 1.6 +/-0.2nm channel spacing and SMSR better than 30dB, is demonstrated by the monolithic integration of a DBR laser array with a PHASAR. The design of a wide-squared spectral response for the PHASAR, as well as the lasers tunability, guaranty wavelength matching between the PHASAR transmission comb and the laser array comb.
