“…Several adaptive OPS technologies have been reported based on tuned fiber Bragg gratings (FBGs) [14], optical polarization splitters [15], semiconductor optical amplifiers [16], [17], waveguide couplers and planar lightwave circuits (PLCs) [18]- [20], MEMS [21], and Opto-VLSI [22]- [24]. However, these techniques have limited tolerance to environmental perturbations, high polarization dependence, and limited numbers of output ports.…”

We propose and demonstrate the concept of a novel 1 Â N lossless adaptive optical power splitter (OPS) structure integrating a software-driven Opto-VLSI processor, optical amplifiers, and an array of 4-f imaging systems. The active area of the Opto-VLSI processor is divided into M pixel blocks driven by multicasting phase holograms and aligned with an M-element lens array and a fiber array, thus forming an array of 4-f imaging systems.Each 4-f imaging system is capable of collimating and adaptively splitting an input optical beam emerging from an optical fiber and then coupling the split beams into different output fiber ports, thus realizing dynamic optical power splitting. The Opto-VLSI processor is driven by optimized multicasting phase holograms that adaptively split an incident laser beam along different angles; thus, user-defined splitting ratios can be achieved. Experimental results show that the optical amplifiers compensate for the splitting and the insertion losses, making the adaptive OPS lossless.

“…Not many dynamic optical splitter/combiner structures have previously been reported [12,13], and none of the reported dynamic optical splitter structures [14][15][16][17][18] have demonstrated the capability of combing optical beams dynamically. In particular, the proof-of-principle 1×2 adaptive optical splitter based on Opto-VLSI processor reported by the authors [18] has low resolution and limited output port counts due to the difficulty in controlling the beam waist.…”

A novel 1×4 reconfigurable optical splitter/combiner structure based on Opto-VLSI processor and 4-f imaging system with high resolution is proposed and experimentally demonstrated. 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. Also, multiple input optical signals are dynamically combined with arbitrary user-defined weights. ©2011 Optical Society of America

“…Recently, only a few dynamic optical splitter structures have been reported. A simple dynamic optical splitter structure has been realized by incorporating an optical amplifier into each output port of a passive splitter [11], [12]. However, such a structure is very expensive and has fundamental limitations, namely, high output noise levels generated by the individual optical amplifiers, and the difficulty in controlling the output power level, since the optical amplifier gain depends on the power level of the split optical signal.…”

Abstract-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.Index Terms-Adaptive optical splitter, beam splitter, liquid crystal devices, optical communication, opto-VLSI processor.
