Theoretical investigation of full optical time division multiplexer based on fiber acousto-optic coupler with loop configuration

摘要

A novel full optical time division multiplexer (OTDM) based on fiber acousto-optic coupler (FAOC) with loop configuration is presented. FAOC with loop configuration is analyzed theoretically, and a 8X2.5 Gb/s OTDM which utilizes FAOC with loop configuration concatenated is investigated. Due to the tunable characteristic between coupled power ratio and operational wavelength of fiber acousto-optic coupler, OTDM in the paper can lower requirements for high performances of devices with respect to the common OTDM methods. Finally, it is pointed that OTDM using several RF drivers can generate simultaneously high speed optical pulses of multi-wavelength. The configuration is feasible in terms of analyzing and simulating theoretically.
