Title

High-Dynamic-Range Hybrid Analog-Digital Control Broadband Optical Spectral Processor Using Micromirror And Acousto-Optic Devices

Abstract

For the first time, to the best of our knowledge, the design and demonstration of a programmable spectral filtering processor is presented that simultaneously engages the power of an analog-mode optical device such as an acousto-optic tunable filter and a digital-mode optical device such as the digital micromirror device. The demonstrated processor allows a high 50dB attenuation dynamic range across the chosen 1530-1565 nm (∼C band). The hybrid analog-digital spectral control mechanism enables the processor to operate with greater versatility when compared to analog- or digital-only processor designs. Such a processor can be useful both as a test instrument in biomedical applications and as an equalizer in fiber communication networks. © 2008 Optical Society of America.
