A 920-1650-nm high-current photodetector

We present novel (InGa)As photodetectors which exhibit 150 mA continuous photocurrent at 2 W power dissipation, A responsivity of 0.97 A/W at 1319 nm is achieved with greater than 60% external quantum efficiency from 920 to 1650 nm, Measured dark currents are below 1 nA and bandwidths of 295 MHz are achieved, These low dark-current devices have utility to applications requiring large output current and large dynamic range.
