Abstract :
The two-dimensional shape of far-field patterns was studied and optimised in a 1.3 μm spot-size converted laser with a pn-buried heterostructure. After optimising the laser structure and using 2 inch wafer processing, the authors improved the shape of the far-field pattern, and the coupling efficiency by using an optical fibre. An average coupling efficiency of -1.4 dB and good uniformity in the laser characteristics were obtained
