POET Technologies already has on-chip lasers
Rainer Klute   3/28/2015 5:50:14 AM
I think it's noteworthy here that POET Technologies already has on-chip lasers as part of their planar optoelectronic technology (POET) platform for monolithic fabrication of integrated electronic and optical devices on a single die – please see their press release as of 2014-03-04.

POET is based on gallium arsenide instead of silicon and offers integration of digital, analog, mixed signal, optics and electronics at high speed and low power consumption. The company is very close to commercializing their technology.

At the moment they are working on a demo ring oscillator showing that the company's inventions indeed make CMOS possible in GaAs, deploying the material's superior properties with respect to speed and power consumption. A demo 50 GHz VCSEL is also in the works, see e.g. their press release as of 2015-02-10.

On-chip lasers have been put on silicon by "glueing" on an GaAs or InP laser, but these researchers claim their's will be easier to make silicon compatible plus consumes very little power.
