Abstract

An electro-optic modulator comprises a resonator comprising a first waveguide having a first end and second end; a first grating at the first end; and a second grating at the second end. An input channel is in communication with the resonator, and comprises a second waveguide having a first end and second end; an input port at the first end; a third grating at the second end; and a first coupler configured to couple light between the second waveguide and the first waveguide. An output channel is in communication with the resonator, and comprises a third waveguide having a first end and second end; an all-pass filter at the first end; a readout port at the second end; and a second coupler configured to couple light between the first and third waveguides. The all-pass filter is configured to adjust a coupling strength between the second coupler and the readout port.

Dependent claims

An electro-optic modulator, comprising:

a resonator comprising:
a first waveguide having a first end and an opposite second end;
a first grating at the first end of the first waveguide;
and
a second grating at the second end of the first waveguide;
an input channel in optical communication with the resonator, the input channel comprising:
a second waveguide having a first end and an opposite second end;
an input port at the first end of the second waveguide;
a third grating at the second end of the second waveguide;
and
a first coupler located along the second waveguide and configured to couple light between the second waveguide and the first waveguide of the resonator;
and
an output channel in optical communication with the resonator, the output channel comprising:
a third waveguide having a first end and an opposite second end;
an all-pass filter at the first end of the third waveguide;
a readout port at the second end of the third waveguide;
and
a second coupler located along the third waveguide and configured to couple light between the first waveguide of the resonator and the third waveguide;
wherein the all-pass filter is configured to adjust a coupling strength between the second coupler and the readout port.
