Integrated optoelectronics based on III-V compound epitaxial heterostructures is an enabling technology for a number of important systems applications. Among which are:
1) IR imaging (medical, astronomy, military, industrial, forensic)
2) Optical signal processing (beam steering, optical correlation, modulating retroreflectors, nonlinear optics, parallel optical computing)
In this talk we present the physics, technology, and applications of two classes of integrated optoelectronics device arrays and systems based on III-V compound epitaxial heterostructures with the above applications in mind:
1) IR focal arrays based on Quantum Well Infrared Photodetectors (QWIPs).
2) Spatial Light Modulators (SLM) based on Quantum Confined Stark Effect Electroabsorption.
These device arrays combine the optimal combination of physics (quantum wells and resonant cavity enhancement design and analysis) materials technology (molecular beam epitaxy, photolithography, Reactive Ion etching) and systems integration (VLSI electronics, Optical Systems).
