Values up to γ= 7× 10^ 6/(Wkm) for the nonlinear parameter are feasible if silicon-on-
insulator based strip and slot waveguides are properly designed. This is more than three …

A cost-effective route to build electrically as well as optically controlled modulators in silicon
photonics is reviewed. The technology enables modulation at bit rates beyond 100 Gbit/s …

We report experimental and theoretical investigations of electroabsorption in a
polydiacetylene, and determine the complete mechanism of third-harmonic generation …

Stimulated emission from silicon-nanocrystal planar waveguides grown via phase
separation and thermal crystallization of SiO∕ SiO 2 superlattices is presented. Under high …

Nonlinear optical transmission and switching phenomena have been observed in directional
coupler devices fabricated from soluble polydiacetylenes. Effects due to both slow thermal …

Prism coupling techniques have been used to evaluate the optical properties of asymmetric
slab waveguides formed from thin spun films of the polydiacetylenes poly (4BCMU) and poly …

We report an epitaxial method for orienting thin films of polydiacetylenes on ordinary
alignment polymers that have been stretched by rubbing. By selectively removing the …

We provide a systematic study on the linear and nonlinear optical properties of silicon
nanocrystals (Si-nc) grown by plasma-enhanced chemical vapour deposition (PECVD) …

Substituted rigid rod‐like polymers (RRPs) can be exploited to control the microscopic order
in, and the fabrication of, devices with potential uses in photonics. The supermolecular …
