An n-channel double heterostructure optoelectronic switch has been demonstrated. As in the case of the p-channel device, there is a high impedance state without light emission and a low impedance state with strong spontaneous emission. The states are changed by optical or electrical signals and a digital optical gain of 14 is observed. The switching voltage is higher and the holding current is lower than in the p-channel case.
