Low-Threshold Optical Bistability in Bulk GaAs Etalons,

Abstract

An optical latch is proposed and integrated monolithically. The basic structure of the device consists of a light amplifying optical switch (LAOS), which is operated as an optical bistable switch and formed by the vertical integration of a heterostructure phototransistor (HPT) and a light emitting diode (LED), and another HPT integrated on the same chip and electrically connected in series to the LAOS device. The additional HPT acts as an optical control which gates the electrical current of the bistable switch. The functionality of the optical latch is experimentally demonstrated. An optical and gate is also demonstrated using a discrete HPT component with a similar configuration as latch circuit but with lower electrical bias.
