Application of guided-wave optics in signal processing sensing
Article Abstract:
A research review is presented on the use of guided-wave optics for signal processing and sensing. Advantages and limitations of the technology are noted and discussed. The guided-wave approach is characterized by an ability to form functions at very high analog bandwidths and digital data rates. Functions performed are: spectral analysis of radio-frequency signals, correlation and matched filtering, code and waveform synthesis, signal delay and storage, and analog-to-digital and digital-to-analog conversion. Sensor applications for guided wave elements fabricated on planar substrates are also reviewed. Waveguides on an integrated optics chip have been used for sensing temperature, humidity, electric field, wave front angle, and optical disk reflectivity. Most applications for signal processing will be for the military. In digital processing, silicon, or GaAs, ICs are adequate and less expensive. Optical processors will have to prove a performance advantage to compete.

Single-mode fibre components
Article Abstract:
The present state of passive and active single-mode fiber components is reviewed. A variety of optical components have been made directly from single-mode fibers. Combinations of single-mode fiber components may be used to construct fiber gyroscopes, fiber Raman lasers, LANs, or coherent lightwave systems. Examples of passive components are: polarizers, directional couplers, filters, and Faraday rotators. Examples of active components are: modulators, polarization controllers, frequency shifters, and amplifiers. A discussion of polarization-maintaining and ordinary single-mode fibers is included. Off-the -shelf single-mode fiber components and devices are expected eventually, but most are still in the laboratory stage.

Telecommunications applications of integrated optics and optoelectronics
Article Abstract:
Available and developing technologies for integrated optical and optoelectronic devices are reviewed. Characteristics and natural areas of application in telecommunications are summarized. Trends and developments in fiber communication systems, services, and architectures are described. There are several major areas where such devices are expected to make a contribution, including: lowering the costs of high-speed network termination equipment; increasing the fraction of the fiber's natural bandwidth that can be available for network usage; and increasing network flexibility.
