Claims29
A resonant optical modulator, comprising:
- an optical resonator;
- a first port optically coupled to the optical resonator with a first time-variable coupling rate;
- a second port optically coupled to the optical resonator with a second time-variable coupling rate;
- and
- a driver for simultaneously modulating the first and second time-variable coupling rates such that a photon population in the optical resonator is substantially constant.
In a resonant optical modulator comprising an optical resonator coupled to first and second ports with first and second coupling rates, respectively, a method for modulating an optical signal, the method comprising:
- modulating the first coupling rate so as to modulate an output signal coupled out to the first port;
- and
- simultaneously modulating the second coupling rate such that a photon population in the optical resonator remains substantially constant.
A resonant optical modulator, comprising:
- an optical resonator having a time-variable loss rate;
- a port optically coupled to the optical resonator with a time-variable coupling rate;
- and
- a driver for simultaneously modulating the time-variable loss rate and the time-variable coupling rate such that a photon population in the optical resonator is substantially constant.
In a resonant optical modulator comprising an optical resonator having a time-variable loss rate and coupled to a port with a time-variable coupling rate, a method for modulating an optical signal, the method comprising:
- modulating the coupling rate so as to modulate an output signal;
- and
- simultaneously modulating the loss rate such that a photon population in the optical resonator remains substantially constant.
In a resonant optical modulator comprising an optical resonator coupled to a plurality of ports, at least two of a loss rate of the optical resonator and coupling rates between the resonator and the ports being time-variable, a method for modulating an optical signal, the method comprising:
- simultaneously modulating at least two of the rates so as to modulate an output signal while keeping a photon population in the optical resonator substantially constant.
