Abstract
An optical-electrical transmitter/receiver (300) with an optical detector (310) for reception which may be made transparent for optical transmission. This permits transmission (320, 330) and reception (310) devices to be positioned in series on a single integrated circuit.
Claims12
An integrated transmitter-receiver, comprising:
- (a) an optical waveguide;
- (b) an optical detector formed in a first portion of said waveguide, said detector switchable between an absorbing state and a transparent state for light of a first frequency;
- and
- (c) an optical transmitter outputting light at said first frequency formed in a second portion of said waveguide.

An optical communication system, comprising:
- (a) a first transmitter with output light of a first frequency;
- (b) a first optical detector for light of said first frequency;
- (c) an optical communication channel with a first end coupled to said first transmitter and to said first detector;
- (d) a second optical detector for light of said first frequency and coupled to a second end of said communication channel remote from said first end;
- and
- (e) a second optical transmitter with output light at said first frequency and coupled to said second end;
- (f) wherein said second detector is switchable between an absorbing state and a transparent state for light of said first frequency.
