Abstract
An optical modulator includes a crystal structure that exhibits polaritonic or excitonic behavior. A shock wave propagates through the crystal structure so as to optically modulate and manipulate a light signal propagating in the crystal structure.
Claims27
An optical modulator comprising:
- a crystal structure that exhibits polaritonic or excitonic behavior;
- and
- a shock wave that propagates through said crystal structure so as to optically manipulate a light signal propagating in said crystal structure.
A method of optical modulation of a light signal comprising:
- providing a crystal structure that exhibits polaritonic or excitonic behavior;
- and
- propagating a shock wave through said crystal structure so as to optically modulate and manipulate a light signal propagating in said crystal structure.
An optical isolator comprising:
- a crystal structure that exhibits polaritonic or excitonic behavior;
- a shock wave that propagates through said crystal structure so as to optically manipulate a light signal propagating in said crystal structure.
