Abstract
Monolithic, cascadable, laser-logic-device arrays have been realized and characterized. The monolithic surface-emitting laser logic (SELL) device consists of an AlGaAs superlattice lasing around 780 nm connected to a heterojunction phototransistor (HPT) in parallel and a resistor in series. Arrays up to 8*8 have been fabricated, and 2*2 arrays show uniform characteristics. The optical logic output is switched off with 40 mu W incident optical input.<>
