Near threshold all-optical backaction amplifier

McRae, Terry; Bowen, Warwick


A near threshold all-optical backaction amplifier is realized. Operating near threshold in an integrated micron scale architecture allows a nearly three orders of magnitude improvement in both gain and optical power requirements over the only previous all-optical implementation, with 37 dB of gain achieved for only 12 μW of input power. Minor parameter adjustment allows narrowband optical filtering.
