M. Fallahi et al., HIGH-POWER EMISSION FROM STRAINED DQW CIRCULAR-GRATING SURFACE-EMITTING DBR LASERS, Electronics Letters, 29(24), 1993, pp. 2117-2118
High power operation of circular-grating surface-emitting distributed
Bragg reflector lasers is demonstrated. The structure is a strained In
GaAs/GaAs double quantum well grown by one step MBE. Circular gratings
are defined by electron beam lithography. A surface emission power ov
er 100mW is obtained.
