Polarization-independent chalcogenide glass nanowires with anomalous dispersion for all-optical processing

Gai, Xin; Choi, Duk-Yong; Madden, Steve; Luther-Davies, Barry


We demonstrate the design and fabrication of square Ge11.5As24Se64.5 (Ge11) nonlinear nanowires fully embedded in a silica cladding for polarization independent (P-I) nonlinear processing. We observed similar performance for FWM using both TE and TM modes confirming that a near P-I operation was obtained. In addition we find that the supercontinuum spectrum that can be generated in the nanowires using 1ps pulse pulses with around 30W peak power was independent of polarization.
