1.5 µm up-conversion device

Abstract
An epitaxially integrated 1.5 to 1 µm up-conversion device is reported. The device consists of a serially connected In0.53Ga0.47As photodiode and InAs0.1P0.9 light emitting diode, grown on InP. The device operation relies first on detecting a 1.5 µm signal by the photodiode and secondly on driving the emitter by the resulting photocurrent, thus achieving the up-conversion.
