Title

Phase-insensitive all-optical transistors based on second-order nonlinearities

Abstract

Cascaded second-order nonlinearities (CSON) and parametric downconversion (PD) are suggested as basis for phase insensitive all-optical transistor (AOT) action using type-II second harmonic generating (SHG) crystals. Both devices are tested using, in the CSON-based AOT, two type II KTP crystals in tandem and, in the PD-based, a SHG crystal and a type II KTP crystal. Both configurations were independent of the phase of the signal, however, the output of the first was coherent, while that of the second was incoherent. Therefore, the PD device output is a coherently amplified version of the input, while in the cascaded device the signal imposes a modulation of the power supply. Experimental fluence gains agree well with numerical modelling.
