Abstract

The structure of buried heterostructure (BH) injection lasers can be improved by allowing for wave leakage from only one side of the active region. BH laser 10 in Figure 1 is first formed by successive growths of layers 14, 16 and 18 on substrate 12, such as by LPE. Layer 16 forms the active layer. Two mesas 20 are formed
