A Very Compact, High Speed and Rugged Acousto-Optic Tunable Filter for Wavelength Division Demultiplexing in Fiber Optic Communication Networks. Phase 1
Abstract
Novel concepts of near-collinear/collinear acousto-optic interactions have been investigated during this SBIR Phase I program. As a result, several new acousto-optic tunable filters have been built and tested. The program is highlighted by: (1) Design, fabrication and experimental demonstration of a novel TeO2 near-collinear acousto-optic tunable filter has been designed, fabricated and tested. The device exhibits a 1.29 nm spectral resolution and a 160 mw RF drive power at 1523 nm. (2) Design, fabrication and experimental demonstration of a novel polarization insensitive TeO2 near-collinear acousto-optic tunable filter. For random input light, an overall insertion loss < 3 dB has been achieved. (3) Design, fabrication and experimental demonstration of a novel collinear acousto-optic tunable filter. The filter exhibits a spectral resolution of 1.12 nm 1523nm with a low insertion loss. (4) The commercial spin-off also has been accomplished at the end of the program. A commercially available fiber pigtailed near-collinear AOTF is shown in the photo. Commercial sales have been generated and new AOTFs have been delivered to customers for applications in optical fiber communications and sensors.
