A novel Opto-VLSI multiband tunable optical filter structure is proposed and demonstrated. Filter tunability is achieved by reconfiguring the holographic diffraction grating of an Opto-VLSI processor, allowing multiple passbands to be independently synthesised. A proof-of-principle three-passband tunable filter of 2 4;nm bandwidth is experimentally verified.
