Abstract :
InGaAs/InP multiple-quantum-well lasers were integrated with low-loss waveguides in the long-wavelength region using a cap-annealing disordering technique which does not require a regrowth process. The coupling efficiency between them does not increase the threshold current of the lasers. The optical loss in the waveguide was 7.8 cm/sup -1/ and was due to free-carrier absorption in the cladding layers.<>
