Resonance and switching in a native-oxide-defined AlxGa1−xAs-GaAs quantum-well heterostructure laser array

Abstract
A twin linear‐array coupled‐cavity AlxGa1−xAs‐GaAs quantum‐well heterostructure laser, a stripe‐geometry coupled two‐dimensional array, is described that, unlike the usual stripe laser, exhibits mode switching and multiple switching (ON–OFF twice) in the light power (L) versus current (I) characteristics (LI) with increasing current.
