Development of vertical cavity transistor laser and microcavity laser
An energy-efficient semiconductor laser is of great interest for the massive data transmission demands in butt computing servers and supercomputing technologies. Currently, commercial vertical-cavity surface-emitting diode lasers (VCSELs) have achieved a data transmission rate of 25 Gbit/s per …

The design and fabrication of an electrically activated photonic crystal microcavity laser
… the dominant cavity mode than spurious modes. Microcavity lasers exploit this stronger coupling by confining photons to a cavity with outer dimensions approximately the size of an optical wavelength. Owing to the strong coupling to the lasing mode, microcavity lasers are distinguished for their …

Cold-cavity measurement of excess optical loss in oxide-confined vertical cavity surface emitting lasers
Microcavity laser design and performance optimization requires a quantitative knowledge of the cavity optical losses. A generalized method using sub-threshold spectral measurements matched to model calculations is demonstrated to determine optical loss in microcavity lasers. Cold-cavity spectral …

Design, fabrication, and characterization of high-speed light-emitting transistors and microcavity lasers
… to ~ 1 ns in light-emitting diodes and diode lasers for the past forty years. In the present work the recombination lifetime demonstrated is able to be “tailored” (reduced) by the provided material system, cavity size, and layout design. In a light-emitting transistor or tilted-charge …
