Laser-Fabricated Delay Lines in GaAs for Optically Steered Phased-Array Radar

Abstract ─ We have used laser direct fabrication techniques to implement optical delay lines on an epitaxial GaAs/AIGaAs substrate. These integrated photonic circuits, which are important for optically-controlled phased-array radar, include asymmetric splitters with various splitting ratios, smoothly curved 90° bends, as well as linear waveguides. The delay lines were tested and found to have the desired delay and a power-output uniformity of ±2-4%.
Louay Eldada (M’88) received the B.S. and M.S degrees from the Columbia University School of Engineering and Applied Science in 1989 and 1991, and the M.Phil. and Ph.D. degrees from the Columbia University Graduate School of Arts and Sciences in 1993 and 1994, all in electrical engineering. In 1990, he worked as a Research Assistant at the IBM East Fishkill laser laboratory. His work involved setting up laser systems for the study of interaction of light with matter In 1991, he engaged in research at the Columbia University Microelectronics Sciences Laboratories in a variety of topics related to laser-induced processing of electronic materials, especially III-V compound semiconductors These topics included materials deposition, patterning, and etching as well as integrated optical devices and photonic integrated circuits modeling, fabrication, and characterization Since 1994, he has been conducting research in optical polymers at AlliedSignal in Morristown, NJ. His work involves the design, fabrication, and characterization of high-performance optical interconnect devices and circuits in polymeric materials Dr Eldada is a member of the Lasers and Electro-Optics Society and the Optical Society of America.
