A 1x2 Adaptive Optical Splitter Based On Opto-Vlsi Processor, Haithem Mustafa, Feng Xiao, Kamal Alameh
Research outputs pre 2011
A 1×2 adaptive optical splitter structure is proposed and experimentally demonstrated. The 1×2 adaptive optical splitter structure is based on Opto-VLSI in conjunction with 4-f imaging system. An Opto-VLSI processor is software driven and capable of splitting an optical beam into different directions when a multicasting phase hologram is uploaded. An input optical signal launched into an input optical fiber port is split and coupled into two output optical fiber ports with arbitrary splitting ratios over a wavelength range exceeding 50 nm.

Research outputs pre 2011
In this paper, the architecture of a photonic-assisted smart antenna for Space-division Multiple Access (SDMA) is described. Antenna beam steering is achieved by generating independent true-time delay (TTD) for each element in the antenna arrays, through the use of an Opto-VLSI Processor in conjunction with a 10-km single mode optical fibre. Experimental results demonstrate RF beam steering in 4-element linear patch antenna array operating at 1.85GHz are presented.

A novel adaptive optical splitter structure employing an Opto-VLSI processor and 4-f imaging system is proposed and experimentally demonstrated. By driving the Opto-VLSI processor with computer generated multicasting phase holograms, an input optical signal launched into an input optical fiber port can be split and coupled into many output optical fiber ports with arbitrary splitting ratios. A proof-of-principle 1 2 adaptive optical splitter structure driven by optimized multicasting phase holograms uploaded onto the Opto-VLSI processor is developed, demonstrating an arbitrary splitting ratio over a wavelength range exceeding 50 nm.
