Abstract :
A new method which uses selective MOVPE growth is proposed to introduce arbitrary phase shifts and applied to 1.55 μm MQW-DFB-LDs. Additional phase shifts produced by the differences in the selectively grown waveguide structures are estimated experimentally, and effective λ/4-phase-shifted 1.5 μm InGaAs/InGaAsP MQW-DFB-LDs are realised
