Research outputs 2011
We propose and experimentally demonstrate a novel high resolution 1×4 adaptive optical power splitter based on the use of an Opto-VLSI processor and a 4-f imaging system with an optimized optical beam waist profile. By uploading optimized multicasting phase holograms onto the software-driven Opto-VLSI processor, an input optical signal is dynamically split into different output fiber ports with user-defined splitting ratios. Experimental results showing dynamic optical splitting over a wavelength range exceeding 50 nm are presented.

Research outputs 2011
A reconfigurable photonic microwave filter structure employing an Opto-VLSI based adaptive optical combiner is proposed and experimentally demonstrated. The Opto-VLSI based adaptive optical combiner is used to combine RF modulated optical signals with a user-defined weight profile to realize a reconfigurable RF photonic filter response. Theoretical simulations are in excellent agreement with the experimental results that demonstrate the concept of the photonic microwave filter structure.
