摘要：
Semiconductor lasers with short integrated mode expanders for efficient coupling to fiat-ended singlemode Fibres are presented. laser-to-fibre coupling efficiencies of-3dB, an improvement of 7dB compared with conventional laser diodes, have been achieved. Simultaneously, the lateral alignment tolerances, for a 1dB reduction of the coupling efficiency have been relaxed to +/-1.8 mu m.
