Third order nonlinearity of 4-dialkylamino-4′nitro-stilbene waveguides at 1319 nm

Abstract

The intensity dependent optical properties of 4-dialkylamino-4′nitro-stilbene polymer channel waveguides were measured at 1319 nm with a pulse modulated Mach–Zehnder interferometer to be n2=0.8×10−13 cm2/W and β2<0.08 cm/GW. This material is promising for all-optical switching at 1319 nm because it satisfies both the W and T figures of merit.
