Laser diodes monolithically integrated with spot-size converters operating at 1.3 μm and having an almost circular far-field pattern and a -1.3 dB butt-coupling-loss-to-fibre with wide alignment tolerance have been successfully fabricated on 2 inch substrates. The overall device length is as short as 450 μm
