Gd. Maxwell et al., DEMONSTRATION OF A SEMICONDUCTOR EXTERNAL-CAVITY LASER USING A UV WRITTEN GRATING IN A PLANAR SILICA WAVE-GUIDE, Electronics Letters, 30(18), 1994, pp. 1486-1487
The authors report the first demonstration of a semiconductor external
cavity waveguide laser, modulated at 2.5 Gbit/s over 100km of standar
d optical fibre using a UV written grating in a planar silica waveguid
e as the feedback element.
