Paper Abstract

1.%μm DFB LD butt-joint integrated with vertical tapered spotsize converter was fabricated by LP-MOVPE. The vertical far field angle (FWHM) was decreased from 34° to 10°, the threshold currents was as low at 19.8mA, the output power was 9.6mw at 100mA without HR coating and the SMSR was 35.8dB. The 1-dBm misalignment tolerance was 3.2μm, while the counterpart of the device without SSC was 2.2μm
