Abstract
A vacuum electronic device is configured to provide electrical current that is configured to be optically modulated by incident light. The vacuum electronic device comprises an optically gated field emission photocathode comprising photoconductive material, an anode comprising a conductive material, and a gap between said photocathode and said anode. The gap comprises vacuum. The anode and photocathode are configured to receive a voltage across the anode and photocathode, such that when said photocathode is illuminated with said light, electrons are emitted from the photocathode and travel through the gap.
Claims18
A vacuum electronic device configured to provide electrical current configured to be optically modulated by incident light, said vacuum electronic device comprising:
- an optically gated field emission photocathode comprising photoconductive material;
- an anode comprising a conductive material;
- and
- a gap between said photocathode and said anode, wherein said gap comprises vacuum,
- wherein said anode and photocathode are configured to receive a voltage across the anode and photocathode, such that when said photocathode is illuminated with said light, electrons are emitted from said photocathode and travel through said gap.
The vacuum electronic device of any of the claims above, further comprising a second substrate, said anode disposed on said second substrate.
