Abstract :
The authors report the first implementation of a buried heterostructure DOES (double heterostructure optoelectronic switch), which incorporates the principles of graded-index, single-quantum-well (GRIN SQW) lasers. Continuous operation and a small signal optical bandwidth of 1.5 GHz were obtained when biased into the on-state. This is consistent with the bond pad side employed. This GRIN SQW DOES laser, fabricated in two-terminal BH form, has been shown to have properties commensurate with the growth and processing parameters employed. Although limited to two-terminal operation, performance is comparable to existing devices with similar designs.<>
