摘要： A method of optical signal amplification. Incident photons are received at a photodetector including a doped semiconductor biased by a power source. The photons generate a change in a reflective property, refractive index, or electrical conductivity of the doped semiconductor. For the change in reflective property or refractive index, a first optical signal is reflected off the photodetector to provide a reflected beam, or the photodetector includes a reverse biased semiconductor junction including the doped semiconductor within a laser resonator including a laser medium, wherein a second optical signal is emitted. For the change in electrical conductivity the photodetector includes a reversed biased semiconductor junction that is within an electrical circuit along with an electrically driven light emitting device, where a drive current provided to the light emitting device increases as the electrical conductivity of the photodetector decreases, and the light emitting device emits a third optical signal.

摘要： A method of forming surface modified substrates includes providing a substrate of material (M) having a bulk portion and an outer surface integrated with the bulk portion. A coating is deposited including metal organic molecules including at least one metal X or particles of metal X onto the outer surface. The coating is laser irradiated with a laser beam, where atoms of metal X diffuse into the outer surface to form a modified surface layer including both M and atoms of metal X on the bulk portion. The modified surface layer has a thickness of at least 1 nm, and a 25° C. electrical conductivity that is at least 2.5% above or 2.5% below a 25° C. electrical conductivity in the bulk portion.
