<p>A laser power converter (LPC) device for receiving incident electromagnetic radiation at a wavelength of about 1550nm, the device comprising: a substrate 60; and an active region 30 comprising an n-doped layer of Indium-Gallium-Arsenide-Phosphide (InGaAsP) 32 and a p-doped layer of InGaAsP 31, the active region being arranged to absorb photons of said incident electromagnetic radiation, there the InGaAsP is lattice matched to the substrate 60. The substrate 60 may comprise Indium Phosphide (InP). The LPC device may also comprise a Distributed Bragg Reflector (DBR) 50 which comprises alternating layers of a first and second material, wherein the first material may be the same material as the active region 30, InGaAsP and the second material may be the same as the substrate 60, InP. Also disclosed is an array of LPC devices, comprising a plurality of LPC devices as above and a plurality of connection means connecting said device together within the array. Also disclosed is a system comprising said array. Further disclosed are methods of: converting electromagnetic radiation comprising using said LPC device; electrical power transmission by inputting electrical power into a laser having wavelength of about 1550nm and outputting said laser to said LPC device; and manufacturing said LPC device by forming said LPC devices constituent features.</p> |
