Patent ID: 7496122

Claim:
A high speed data channel including one or more optical channels comprising: a high speed integrated optical driver comprising: a field effect transistor (FET) driver circuit on an integrated circuit (IC) chip, a passive element coupled at one end to an output of said FET driver circuit; a vertical cavity surface emitting laser (VCSEL) diode coupled at one electrode to said passive element, and a bias supply biasing said VCSEL diode; an optical medium driven at one end by said high speed integrated optical driver; and a high speed integrated photodetector comprising: a semiconductor layer, an ultrathin metal electrode on said semiconductor layer, said ultrathin metal pattern having a thickness less than 2000 Å and forming a Schottky barrier diode junction in said semiconductor layer, and a quantum well formed in said semiconductor layer between said ultrathin metal pattern and said Schottky barrier diode junction, said quantum well containing a two dimensional electron gas.
