Good morning

Thank you for all your contributions.
In any case, a second platform is under development and I look forward to learning more about it.

A new patent granted in 2020 to Geoff W. Taylor and POET Technologies, Inc.

Split-electrode vertical cavity optical device
Patent number: 10811841
Type: Grant
Filed: March 6, 2017
Date of Patent: October 20, 2020
Assignee: POET Technologies, Inc.
Inventor: Geoff W. Taylor

BACKGROUND
1. Field
The present application relates to semiconductor integrated circuits that implement a variety optoelectronic functions (such as optical emitters, optical detectors and optical switches) and electronic functions (such as heterojunction field effect transistors and bipolar field effect transistors).
2. State of the Art
The present application builds upon technology (referred to by the Applicant as “Planar Optoelectronic Technology” or “POET”) that provides for the realization of a variety of devices (optoelectronic devices, logic circuits and/or signal processing circuits) utilizing inversion quantum-well channel device structures as described in detail in U.S. Pat. No. 6,031,243; U.S. patent application Ser. No. 09/556,285, filed on Apr. 24, 2000, etc, etc, all of which are hereby incorporated by reference in their entireties.
The active device structures are preferably realized with a material system of group III-V materials (such as a GaAs/AlGaAs).
