Patent Images
1. An opto-electronic device, comprising:
- a substrate;
first and second waveguides formed on the substrate;
a first grating coupler formed in the first waveguide to couple input light incident to the substrate into the first waveguide;
an optical resonator in optical communication with the first and second waveguides to exchange light;
an optical modulator coupled to the first waveguide and operable to modulate light in the first waveguide in response to an electrical modulation signal;
a photodetector positioned on the substrate to receive and convert an optical output from the second waveguide into an electrical signal; and
an electrical link coupled between the photodetector and the optical modulator to produce the electrical modulation signal from said electrical signal.
