ABSTRACT:
A method of and apparatus for high speed modulation of a laser by controlling stimulated emission in the direction transverse main output. Because gain in either direction is derived from the same pool of excited carriers, lasing in the transverse direction depletes gain available in the longitudinal direction. The control of the forward output is achieved using either (1) transverse transmission regions depending on the applied bias or (2) transverse absorbing regions.
