Tuneable Microwave Photonic Filter Incorporating Wavelength Spacing Programmable, Arrayed Micro-Mirror Based Optical Filter

We demonstrate a novel, tuneable microwave photonic FIR filter scheme incorporating a wavelength spacing tuneable, multiwavelength filter based on a programmable, arrayed micro-mirror filter device. By controlling the filter wavelength spacing, free resonance RF frequency tuning is achieved over a range of 2.3 GHz.
