Electroabsorptive/-Refractive Effects in Asymmetric Step Quantum Wells and BRAQWET Structurestric fields and/or currents to the structure. This is technologically important for devices, such as electrically controlled intensity and phase modulators, directional couplers and devices for wavelength multiplexed systems.

Electrooptical Modulation in Vertical Multiple Quantum Well MicroresonatorsThe electrical current of this hybrid device is kept low by using undoped AlGaAs barrier layers cladding the active MQW material. For high-speed operation, we propose a novel traveling-wave modulator with a special coplanar metallic waveguide structure. Electrooptical modulation is studied using a T

Criteria for the Use of Nonlinear GaAs Etalons for Threshold Logicry devices. It is within this context that work on GaAs etalons has been historically pursued [1] and the demonstration of transistor action and bistability [2] have been important events. The systems aspect of optical computing has meantime broken new ground and we need figures of merit for such de

The Design of Quasi-Periodic Fourier Plane Array Generatorsning the array generator as a quasi-periodic computer generated hologram. In this way an even distribution of noise is obtained while the required diffraction orders are left as tightly sampled spots. Using the method of generalised error diffusion several different quasi-periodic 4 × 4 array genera

Holographic Interconnect Components for Optical Processing Systemss paper reviews the various types of holographic interconnect components that have been used in a series of optical parallel digital processing experiments at Heriot-Watt University. Both high-level and low-level space-invariant fan-out elements are covered, along with components for space-variant i

Binary, Multilevel, and Hybrid Holographic Optical Array Illuminators optical components have been designed and demonstrated that convert a single laser beam into a regularly-spaced array of . equal-intensity light spots. Space-variant array illuminators, which form the spot array in a Fresnel plane or an image plane of the aperture are in general easy to design and
