Abstract:
1. A semiconductor light emitting apparatus having a substrate, said apparatus comprising: an active layer located between a first-conductivity-type first cladding layer, and a second-conductivity-type second cladding layer on said substrate; a pair of opposing first recesses forming a stripe-patterned ridge which define a major current path formed over the active layer and extending into the second cladding layer, and a second recess disposed on the outer side of at least one of said first recesses, each of said first and second recesses being formed to a depth while keeping said active layer unreached; a first-conductivity-type current blocking layer formed so as to extend over the inner surfaces of said first and second recesses, and a second-conductivity-type contact layer formed over said current blocking layer; wherein a light emitting portion causing light emission is provided by current which flows through said major current path; and a thyristor structural portion is provided by a stack formed at said second recess comprising said second-conductivity-type contact layer, said first-conductivity-type current blocking layer, said second-conductivity-type cladding layer, said active layer and said first-conductivity-type first cladding layer.
