| Abstract: | A ridge-type semiconductor laser with selectively proton-implanted cladding layers for separate confinement of horizontal transverse modes and carriers is proposed, and lasing characteristics are simulated. Light is confined by the proton-implanted n-cladding layer; carriers are confined by the proton-implanted p-cladding layer. It is found that light output operating in the fundamental transverse mode is enhanced and threshold current is decreased. |
