Large optical cavity AlGaAs injection lasers with multiple active regions

Abstract

A new type of AlGaAs injection laser is described. The structure consists of alternating p- and n-type layers of GaAs and AlxGa1−xAs . The electrical mode of operation of the device is that of a Shockley diode (SCR). Optically the device operates as a large optical cavity. Single transverse mode operation was observed with optical cavities larger than 4 µm.
