56 dB Parametric Gain in AlGaAs-on-insulator Nanowaveguides

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate broadband optical parametric amplification in an 11-mm-long AlGaAs-on-insulator waveguide with pulsed pumping at 1550 nm. We achieve a net on-chip gain of 56 dB, the highest demonstrated parametric gain in integrated platforms.
