Abstract :
0.8 mu m band laser-diode modules have been developed for coupling to fibres with a relative refractive-index difference ( Delta ) as high as 2.3%. A coupling loss of 3.1 dB, fibre output power over 35 mW, and excellent temperature stability in the range from -10 to 60 degrees C were realised using a thermally-diffused expanded core fibre.
