PCT No. PCT/EP92/01175 Sec. 371 Date Dec. 24, 1992 Sec. 102(e) Date Dec. 24, 1992 PCT Filed May 26, 1992 PCT Pub. No. WO92/22111 PCT Pub. Date Dec. 10, 1992.An optical device includes a semiconductor laser monolithically integrated on a substrate having a branched cavity extending above a plane that is coplanar with a base surface of the substrate, and an adjustable optical power light source for radiating light into the cavity of the semiconductor laser thereby controlling the operation of the semiconductor laser optically.
