Circular-grating surface-emitting distributed Bragg reflector lasers on an InGaAs-GaAs structure for 0.48-μm applications
IEEE Journal of Selected Topics in Quantum Electronics（1995）
摘要
In this paper, we report on the design and fabrication of electrically-pumped circular-grating surface-emitting DBR lasers for operation in the 0.98-/spl mu/m wavelength range. The layer structure with InGaAs-GaAs-AlGaAs strained multiquantum-wells was obtained by one-step epitaxial growth. Circular gratings are defined by electron-beam lithography around circular gain sections of different diamet...
