1×N wavelength selective adaptive optical power splitter for wavelength-division-multiplexed passive optical networks

•We propose a wavelength selective adaptive optical splitter for passive optical access network applications.•The input wavelength channels can be independently split into N output ports with desired splitting ratios.•The proposed wavelength selective adaptive optical splitter has been experimentally demonstrated.

In this paper, a 1×N wavelength selective adaptive optical power splitter (WS-AOPS) suitable for wavelength-division-multiplexed passive optical network (WDM-PON) systems is proposed and experimentally demonstrated based on the use of an Opto-VLSI processor. The input signals with different wavelengths can be split and coupled into N output ports with variable splitting ratios. A proof-of-principle 1×2 WS-AOPS structure driven by optimized multicasting phase holograms uploaded onto the Opto-VLSI processor is developed, demonstrating an arbitrary splitting ratio for each input wavelength channel over C-band.
