Abstract
A pumped sensor system includes a substrate with a first layer formed thereon and doped for a first type conduction and a second layer doped for a second type conduction, whereby the first and second layers form a silicon light detector at an up-conversion wavelength. A ternary rare earth oxide is formed on the second layer and crystal lattice matched to the second layer. The oxide is a crystalline bulk oxide with a controlled percentage of an up-conversion component and a majority component. The majority component is insensitive to any of pump, sense, or up-conversion wavelengths and the up-conversion component is selected to produce energy at the up-conversion wavelength in response to receiving energy at the pump and sense wavelengths. The layer of oxide defines a light input area sensitive to a pump wavelength and a light input area sensitive to a sense wavelength.
