Abstract:
A monolithic integrated edge-emitting semiconductor laser structure comprising:a first laser structure havinga first substrate;an n-type first cladding layer formed on said substrate;a first confinement layer, a first active layer for emitting light of a first wavelength, and a second confinement layer forming a first active region on said first cladding layer;a p-type second cladding layer formed on said second confinement layer above said first active region,a second laser structure havinga fusion layer for bonding said first laser structure and said second laser structure,an n-type first contact layer formed on said fusion layer;an n-type third cladding layer formed on said first contact layer;a third confinement layer, a second active layer for emitting light of a second wavelength, and a fourth confinement layer forming a second active region on said third cladding layer;a p-type fourth cladding layer formed on said fourth confinement layer above said second active region,a p-type second contact layer formed on said fourth cladding layer,a first contact and a second contact which enable biasing of said first active region for emission of light of said first wavelength, anda third contact and a fourth contact which enable biasing of said second active region for emission of light of said second wavelength.
