New Integrated Optical Components for Broadband Communication Systems

摘要

The objectives of this project was to design and fabricate polarization insensitive semiconductor optical amplifiers, design and fabricate planar optical isolators, investigate the possibility of their integration. Quantum well polarization insensitive semiconductor optical amplifiers in GaInAsP and AlInGaAs at 1300 nm, and the latter at 1550 nm were designed and tested, at Minnesota. Planar isolators in the Mach-Zehnder configuration were designed and tested at Columbia. The integration issues were investigated and a key component, the planar polarizer, was designed. Sputtered films for integration of the isolator were also investigated. For broadband system components, Minnesota examined the co-directional coupler, and arrived at a synthesis technique which does both amplitude and phase response. Columbia has examined the simulation of optical components and made considerable progress in practical simulation of mixed polarization devices. The report briefly outlines the results.
