Abstract
Spatial optical solitons have been receiving an increasing amount of attention due to their potential application for all-optical interconnects. Bright solitons arise as a compensation of natural diffraction of an optical beam by a self-focus nonlinearity. They have been observed in semiconductor, glass and CS2 waveguides at powers of 500W, 400KW and 500KW [1,2,3]. Recently, conjugated polymer poly[2,4-hexadiyn-1, 6-diol-bis(p-toluenesulfonate)] (PTS) was reported to have large positive nonlinearity (2.2×10-12W/cm2) and a very small two-photo absorption at around 1.6μm [4]. The large off-resonant positive nonlinearity would allow the one dimensional (ID) spatial soliton at a practical power level on PTS slab waveguide. We now report the preparation and waveguiding of PTS films.
