The study of volume gratings has led to useful applications in many areas of optics, including integrated optics, acousto-optics, and holography. In most situations the coupled-mode analysis of volume holograms established by Kogelnik1 accurately describes the diffraction behavior of a thick hologram and predicts a diffraction efficiency that is a periodic function of the index perturbation amp...

Two active Mach-Zehnder interferometers are integrated in a monolithic InP/InGaAsP photonic integrated circuit. Together they form a crucial component for optical signal processing: an optical memory element or set-reset flip-flop. The switching time for this initial device is approximately 200 ps. The photonic integrated circuit contains active and passive optical components, including electro...

We present what is believed to be the first packaged module incorporating polarization-based beam-forming optics integrated with an optoelectronic-VLSI device. The chip has multiple quantum-well modulators and detectors that are flip-chip bonded onto a silicon CMOS integrated circuit. In the assembled module a polarization-selective computer-generated hologram converts linearly polarized light ...

This paper lays out a road map for computer-integrated design and manufacture of building-specific cladding systems, describing the key implementation phases and highlighting domains (supply chain organization, software vendors, suppliers, process modellers, etc) involved in each phase. It takes a holistic look at the way forward, identifying that such a long-term transformation will need to be...

Modern optics is a field which combines basic physics with industrial applications, especially in the domains of telecommunication and sensor development. The grating coupler, an important device of integrated optics, is proposed as a model system. It is particularly appropriate for discussing basic topics such as wave-guiding and diffraction, and can be used for demonstrating important applica...

Optical interconnections made using two-dimensional arrays of top-surface-emitting microlasers and integrated free-space optics are discussed for use in chip-to-chip communications. A demonstration setup with a 2 x 2 array of lasers is presented. System parameters, such as light efficiency, the number of data channels, thermal effects, power requirements, and the issue of hybrid integration of ...

Chemo—optical micro-sensing systems, whether based on fiber optics or integrated optics show promising prospects. The physical principles underlying chemo—optical waveguide sensors are discussed with the accent on linear evanescent field sensors. The role of the chemo-optical transduction layer is emphasized. Restriction of the freedom of design by technological uncertainties is briefly dealt w...

Our recent results on the demonstration of on-chip mode-division multiplexing functionalities are reviewed, with a special emphasis on the feasibility of nonlinear all-optical signal processing on the silicon-on-insulator (SOI) platform. Mode-selective parametric processes are demonstrated in a 4-mm long SOI waveguide. OCIS codes: (130.3120) Integrated optics devices; (030.4070) Modes; (130.740...

We theoretically discuss the interaction of neutral particles (atoms, molecules) with surfaces in the regime where it is mediated by the electromagnetic field. A thorough characterization of the field at sub-wavelength distances is worked out, including energy density spectra and coherence functions. The results are applied to typical situations in integrated atom optics, where ultracold atoms ...

An integrated expert system has been developed to solve the charge particle beam optics problems [1,2]. The optics elements are a drift space, a bending magnet, a quadrupole, a sextupole, an octupole, a solenoid, an accelerating tube and some elements introduced by the users. BEAM_LINER is coded by the C++ language and the UNIX operation system with a graphical user-oriented interface on the PC...
