Paper Abstract

In this paper, we report on the design and fabrication of electrically-pumped circular-grating surface-emitting DBR lasers for operation in 0.98 micrometers wavelength range. The layer structure consists of InGaAs/GaAs/AlGaAs strained multi-quantum-wells grown by one step epitaxial growth. Circular gratings are defined by electron-beam lithography around the circular gain sections. The effect of various parameters are discussed and the most recent results are presented.
