Channeled-substrate-planar-structure semiconductor lasers with lateral-evanescent-field distributed feedback

Abstract
GaAs‐AlxGa1−xAs channeled‐substrate‐planar‐structure lasers with lateral‐evanescent‐field distributed feedback are fabricated by using one‐step liquid‐phase epitaxy. The diodes operate stably in single‐transverse (fundamental) and longitudinal modes at room temperature under pulsed operation.
