Abstract
Amorphous silicon carbide may be doped with one or more ions such as vanadium and these ions may radiate light if excited, for example, using optical or electrical pumping. A single photon light source may be formed from a single such ion that is pumped or from a plurality of ions that are pumped if light from only one ion is collected, e.g., using an aperture or pin hole. Such single photon sources may possibly be use in quantum computing, quantum sensing and/or quantum telecommunications.
Claims18
A light source comprising:
- a light emitter comprising amorphous silicon carbide having an ion therein;
- and
- a pump configured to direct energy to said amorphous silicon carbide to excite said ion into a higher energy state such that said ion emits light,
- wherein said ion comprises a vanadium ion.
1 more element
A light source comprising:
- a host comprising amorphous silicon carbide;
- a vanadium ion in said host of amorphous silicon carbide;
- and
- an optical pump configured to output light that is directed to said amorphous silicon carbide to excite said vanadium ion therein, said light incident on an area of said amorphous silicon carbide, said vanadium ion comprising the only vanadium ion within said area.
