All‐optical switching—controlling light with light—has the potential to meet the ever‐
increasing demand for data transmission bandwidth. The development of organic π …

Reflecting rapid growth in research and development on organic/polymeric electronic and
photonic materials and devices, Introduction to Organic Electronic and Optoelectronic …

A long-standing prediction is that the refractive index of organic materials possessing
extended electron conjugation can be changed instantaneously by exposure to light, making …

We report femtosecond measurements of the dispersion in the nonlinear refraction and
multiphoton absorption in polydiacetylenes, specifically in PTS [polymer poly (bis para …

We observed the photonic band structure of one-dimensional photonic crystals using a white-
light Michelson interferometer. In one-dimensional photonic crystals with a structural defect …

Detailed measurement of spectral broadening in a poly-[2, 4 hexadiyne-1, 6 diol-bis-(p-
toluene sulfonate)](PTS) single crystal owing to self-phase modulation was performed as a …

We show that a single thin layer (thickness much less than an optical wavelength) of
nonlinear optical material can display optical bistability solely as a consequence of local …

By optical modulation of the reflectivity of an intracavity nonlinear Fabry–Perot
semiconductor mirror, the pulse train from a passively mode-locked picosecond Nd: YVO_4 …

In this work, we present a study of the third-order nonlinearities of a novel organic material, a
derivative of the molecule 2-amino-1, 2, 3 triazole-quinone. The absorptive and refractive …

The linear and nonlinear response of Fabry–Perot etalons containing a polymer microcrystal
solution was studied using the pump–probe technique with a white-light continuum probe …
