Semiconductor laser
摘要:
An AlGaInP-based buried-ridge semiconductor laser includes an n-type GaAs current blocking layer 8 buried in opposite sides of a ridge stripe portion 7 which is made of an upper-layer portion of a p-type AlGaInP cladding layer 4, p-type GaInP intermediate layer 5 and p-type GaAs contact layer 6. The ridge stripe portion 7 includes tapered regions 7a having the length of L1 at cavity-lengthwise opposite ends of the ridge stripe portion 7.
