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.
Because of the economic and technical advantages, laser processing technology has been developed rapidly in recent years. Jilin Province Laser Institute laser processing center set up a laser cutting production line, a laser heat- treatment production line, and a laser marking machine. In this paper we describe applied examples of laser cut, laser heat-treatment and laser marking.
