    We review the theory of the nonresonant optical Stark effect in semiconductors. The solution of the stationary equations allow to see the origin of the energy shifts and changes in the oscillator strengths. The solutions for pulsed pump and probe beams are discussed.

High-speed phenomena in photonic materials and optical bistability: Marchthe Hague, the Netherlands Author: D Jäger ; European Physical Society. Optical Bistability: Controlling Light with Light focuses on optical bistability in nonlinear optical systems. Emphasis is on passive (non-laser) systems that exhibit reversible bistability with input intensity as the hysteresis variable, along with the physics and the potential applications of such systems for nonlinear optical signal processing.

In this work, we have demonstrated experimentally the electro-optical switch, logic and memory operations at the speed of as fast as nanosecond region, utilizing the mode-hopping phenomenon of a laser diode.

We have also confirmed the hysteresis (wavelength bistability) region being still effective under even such a high : Wakao Sasaki, Hirokazu Nakayama, Masahiro Mitsuda, Tatehisa Ohta.

Bistability (BS) and self-pulsation (SP) phenomena in silicon microring resonators (MRR) with intense CW light injection are studied. Several nonlinear optical effects including Kerr effect, two-photon absorption, free carrier absorption and free carrier dispersion are taken into account.

The threshold optical intensity of BS and SP is derived from the coupled mode theory and a linear. Optical bistability occurs when the effects of nonlinear behavior of materials cause hysteresis in the transmission and the reflection of a device.

In particular, we report on the experimental demonstrations of guided-wave optical bistability and limiting in an input distributed coupler; butterfly bistability of an input-output grating-coupler combination; all-optical tuning of a distributed feedback reflector; and enhancement of bistability effects by the use of a counter-propagating feedback by: 1.

In this work, we demonstrate the optical bistability phenomena in 1D Ag-Al 2 O 3 photonic crystal at visible frequencies. First, we show the linear transmission properties of designed 1D Ag-Al 2 O 3 PCs. Then a Z-scan experimental technique will be used to show the enhanced nonlinear optical response of the proposed geometry.

The application of photonic crystal technology allows us to design waveguides, couplers, and routers on a much smaller scale than previously possible, thus allowing the design of high-density integrated circuits Applications of this work are in telecommunications, e.g.

for devices that manage high-speed, high volume data (e.g. internet) traffic. To illustrate the optical bistability phenomenon in plasmonic nanostructure, we consider a spherical/cylindrical nanoparticle illuminated by an electric field and embedded in a homogeneous medium as shown in Fig.

Lugiato. A bistable device will remain stable in two optical states, one of high transmission and another of low transmission, depending upon the intensity of the light passing through it. In the low transmission state, the path length through the material, which is placed between two partially reflecting mirrors, results in refraction that dims the exiting beam.

The invention of the laser in enabled us to examine the behavior of light in optical materials at higher intensities than previously possible.

Many of the experiments carried out made it clear that optical media do in fact exhibit nonlinear behavior. The field of nonlinear optics comprises many fascinating phenomena.

Various logic functions can be implemented using suitable optical feedback. The switching characteristics can be controlled by the internal structure of the epitaxial layers of the device.

The geometrical characteristics of the film and grating coupler have been optimized. This device has been studied in the nonlinear regime using nanosecond and picosecond exciting pulses.
