Abstract
Disclosed are optical modulators that have two coupling paths or structures between an input port to an output port, at least one of which includes an optical resonator.
Claims19
An optical modulator, comprising:
- a first optical waveguide comprising an input port and a through port, the input port for receiving an input signal;
- a first optical resonator optically coupled to the first optical waveguide;
- a second optical waveguide optically coupled to the first optical resonator and comprising a drop port;
- and
- a coupling structure optically coupling the first optical waveguide to the second optical waveguide.

An optical modulator, comprising:
- an optical input port for receiving an input signal;
- an optical through port;
- an optical drop port;
- and
- an optical resonator structure coupling the input port to the through port and the drop port,
- wherein a transfer function from the input port to the through port comprises a transmission zero at a frequency of the input signal in a first modulation state, and a transfer function from the input port to the drop port comprises a transmission zero at the signal frequency in a second modulation state.

A wavelength-selective optical modulator, comprising:
- an optical input port;
- an optical output port;
- a first path connecting the optical input port to the optical output port, the first path comprising at least two optical resonators;
- and
- a second path connecting the optical input port to the optical output port via a structure outside of the first path.
