Abstract

A multi-order Bragg scattering of light with direct transitions between optical modes in uniaxial crystals is considered. The performed analysis has revealed optical nonlinearity governed by an external electronic signal. All-optical multi-bit registers are proposed.

All-optical switching and logic based on a two-phonon light scattering

Alexandre S. Shcherbakov, Eduardo Tepichín-Rodríguez

We consider physical principles of a two-phonon light scattering in crystals in a special case, when direct transitions between all the orders of scattering are allowed and, moreover, the probabilities of these transitions can be regulated electronically. The exact and closed analytical model for describing this process is presented. The feasibility of exploiting such a phenomenon for creation of an all-optical logic is substantiated. A few possibilities of arranging the optical logic gates are revealed. Fulfilling a set of logic operations is algorithmically analyzed and estimated.

An all-optical 4-bit register based on a four-order scattering of light by coherent acoustic phonons in single crystals

A. S. Shcherbakov, E. Tepichin Rodríguez, Arturo Aguirre López

A specific case of a four-order non-collinear light scattering in anisotropic media is presented.Compared to our previous studies, an innovation lies in the fact that now we consider passing just the quartet of incident light waves through a single crystal that is perturbed by a coherent stream of acoustic phonons.The exact and closed analytical model for describing this strongly nonlinear phenomenon is developed.In fact, a specially designed regime of a four-order light scattering, when transitions of four input light beams into four output light modes are allowed and electronically controlled, is examined.The feasibility of applying such an effect to perform an all-optical switching is analyzed.An opportunity for arranging the digital 4-bit register is revealed and algorithmically analyzed.

All-optical switching via four-wave mixing Bragg scattering in a silicon platform

Yun Zhao, David Lombardo, Jay Mathews +1 more

We employ the process of non-degenerate four-wave mixing Bragg scattering to demonstrate all-optical control in a silicon platform. In our configuration, a strong, non-information-carrying pump is mixed with a weak control pump and an input signal in a silicon-on-insulator waveguide. Through the optical nonlinearity of this highly confining waveguide, the weak pump controls the wavelength conversion process from the signal to an idler, leading to a controlled depletion of the signal. The strong pump, on the other hand, plays the role of a constant bias. In this work, we show experimentally that it is possible to implement this low-power switching technique as a first step towards universal optical logic gates, and test the performance with random binary data. Even at very low powers, where the signal and control pump levels are almost equal, the eye-diagrams remain open, indicating a successful operation of the logic gates.

All-optical switching scheme using a three-level atomic system within photonic crystals

Hiroyuki Nihei, Atsushi Okamoto

We propose all-optical switching schemes using a single three-level atomic system placed within a 3D photonic crystal that exhibits a complete 3D photonic band gap. The optical schemes we propose can be classified into two types with respect to a physical process that causes the switching effect. One switching type is mediated by changing an atom-field coupling strength. The other switching type is mediated by controlling quantum interference. Furthermore, we consider conditions of realizing a wide range of signals, which contributes to an improvement of the Signal to Noise ratio. The phases and strengths of the external laser fields required for the all-optical switching are revealed. Next, we estimate their switching times. Using these results, we propose the fastest scheme for every configuration of the atomic system, which is important for realizing a high-speed optical memory or switching device on an atomic scale that can be used in novel optical integrated systems, such as quantum computers.

All-optical switches and bistable devices using high- Q photonic crystal nanocavities

Takasumi Tanabe, Akihiko Shinya, Eiichi Kuramochi +2 more

We review our recent progress on all-optical switching and bistability using ultrahigh-Q photonic crystal nanocavities. We also discuss all-optical logic gate operations. Because photonic crystal nanocavities can strongly confine photons in a small area for a long time, light can efficiently interact with dipoles. As a result, optical nonlinearities occur at a very low input. Optical nonlinearities are essential as regards all-optical switching and bistability, because they dynamically change such material properties as refractive index. We demonstrate all-optical switching at an operating energy of less than 100 fJ, and bistable operation at less than ~100 μW. In addition, these devices are small and so can operate at a reasonably high speed (~100 ps).
