Summary form only given. Poly [bis(p-toluene sulfonate)] of 2,4-hexadiyne-1,6-diol (PTS) is a conjugated polymer which exhibits strong /spl Pi/-electron delocalization that leads to a large nonlinear optical effect. We present experimental results on

We have demonstrated by changing the temperature scan speed the possibility of achieving different temperature profiles, therefore different wave-vector mismatch along the LiNbO/sub 3/ optical channel waveguide. We can control the sign of the induced

We observed spatial modulational instabilities of nonlinear eigenmodes in a lithium niobate slab waveguide during second-harmonic generation and measured their gain.

Cascading refers to phenomena associated with the multiple interchange of photons between beams which interact parametrically via second order nonlinearities. [1] Although second harmonic generation (SHG) is the most common example, it also involves

The nonlinear susceptibility of the first soluble polydiacetylenes was measured by Chance1 in 1980, and poly(3BCMU) and poly(4BCMU) were among these. Most of the work done on χ(3) in poly(3BCMU) and poly(4BCMU) since have been measurements taken in

Nonlinear Guided Waves and Their Applications.
The mixing of counter propagating guided waves to generate second harmonic radiation normal to the surface was initially demonstrated in Ti in-diffused LiNbO3 waveguides over a decade ago.[1] Although the signals were too small to be useful in practi

Second-harmonic generation (SHG) in waveguides has been important for years as a method of obtaining a compact, coherent blue light source. Recently, this field has received new attention due to the possibility of using cascaded χ(2)-effects for all
