ABSTRACT:
A semiconductor injection laser is provided with an integrated optical injector means on same substrate as the laser which has an optical emitter region noncolinear with the axis of optical emission from the laser but optically coupled to the laser at one or more points along its length. The optical injector means is independently operative prior to or simultaneously with the independently operated laser to inject radiation into the laser optical emitter region to decrease the response time of the laser to pulsed current modulation.
