TRANSIENT-RESPONSE OF OPTOELECTRONIC INTEGRATED BISTABLE DEVICE

In this paper, the transient response of an optical bistable device wi th optically controlled set and reset functions is analyzed, The devic e is made from a vertical integration of two heterojunction phototrans istors (HPT's) and a laser diode (LD). One of the HPT's (HPT-A) is int egrated just above the active layer of the LD and is utilized in the s et operation, while the other HPT (HPT-B) is used to achieve the reset operation, The effect of the various device parameters on the set and reset operations is outlined, Finally, expressions for the rise time during the setting, and fall time during the resetting conditions are derived.
