Laser diodes monolithically integrated with spot-size converters fabricated on 2 inch InP substrates

Abstract
Laser diodes monolithically integrated with spot-size converters operating at 1.3 µm and having a 7 × 11 degree far-field pattern and a –2.4 dB coupling loss to fibre with good alignment tolerance have been successfully fabricated on 2 inch substrates with satisfactory uniformity and reproducibility.
