Abstract
Optical laser amplifier devices are formed integrally with spontaneous emission filters. The filtering function is accomplished by a laser amplifier whose output is employed to quench the signal generated by a laser. The quenching of the laser is performed in direct proportion to the stimulated emission component of the laser amplifier output signal. Since the stimulated emission component represents the output signal minus any spontaneous emission noise, the output signal generated by the laser is an amplified, inverted version of the input signal without the noise components. In the preferred embodiments, optical waveguides are employed to form the laser amplifier and the laser is either a horizontal cavity edge emitting laser or a vertical cavity surface emitting laser (VCSEL).
