Dynamic characteristics of a 1.3 µm laserdiodeintegrated with a spot-size converter coupled toa silica planar lightwave circuit

Abstract
Dynamic characteristics are clarified for a laser diode integrated with a spot-size converter coupled to a silica planar lightwave circuit. The laser was developed with a butt-jointed selectively grown spot-size converter. A maximum coupling efficiency of –0.74 dB was achieved. Bit error rate performances are estimated to clarify the allowable reflection when optical feedback from the fibre output end occurs.
