We present the design and numerical simulation results for a silicon waveguide modulator based on carrier depletion in a linear array of periodically interleaved PN junctions that are oriented perpendicular to the light propagation direction. In this geometry the overlap of the optical waveguide mode with the depletion region
survey of recent work on optical waveguide modulators in electrooptic, acoustooptic, and magneto"optic mate- rials is presented. Methods for realizing waveguiding layers in modulating materials and various modulator configurations are considered. 1. IX"TROD7JC'TION. H. IGH-speed light modulators and beam deflectors.

An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators,
Electromagnetic carrier: E(t) = eAcos(?0t +?). • Modulation of A, ?0, or ? leads to AM, FM and PM, respectively. • In the digital case, they are referred to as ASK, FSK, and PSK. ASK is also called on–off keying. • Role of a modulator is to convert a CW input into an optical signal that mimics applied electrical signal. • A good
We describe a GaAs electro?optic channel waveguide which can be used as a high?speed modulator with a potential bandwidth of 1 GHz. A narrow Schottky?barrier strip permits beam trapping to be controlled by an applied voltage. Ninety?five percent amplitude modulation has been obtained with a minimum bandwidth of

laserex12.in : Silicon p-i-n Waveguide Modulator. Requires: Blaze/Quantum/Laser Minimum Versions: Atlas 5.24.1.R. This example demostrates a simulation of Si p-i-n modulator using a WAVEGUIDE statement. The modulation mechanism is based on electroabsorption by free-carriers, which are injected into the
