Abstract

The spontaneous emission by ballistic electrons which traverse a super lattice yields as many as 5·108/sec IR photons for an injected current of 100μA into a 5×20μm2 device. Based on this result we obtain the rate of stimulated emission and the gain of an electromagnetic wave. We find that the threshold current density for net wave amplification is about 104AA/cm2. An analysis of the device as a traveling wave amplifier and an oscillator is also presented.
