Paper Abstract

In this paper, a short polarization-maintaining Er:Yb co-doped fiber laser is experimented. A pair of FBGs are written in the Er:Yb co-doped sensitive fiber using UV beams. A 976nm pumping laser diode is used, and output wavelength is selected by two FBGs. The PM Er:Yb co-doped fiber is used to main the orthogonal polarizations SM lasing stability. The SM operation in each wavelength has been verified. On the basis of previous short cavity fiber, a simple DBR dual wavelength fiber laser array has been designed and experimented. Two sections of short Er:Yb co-doped fiber cavities are pumped by a 976nm LD simultaneously. The pump laser is splitted to pump each Er:Yb co-doped fiber. It used a WDM coupler at 1550nm to connect the output port of two DBR fiber laser, an isolator is spliced to the common arm of the WDM and used as the output port. The dual wavelength spacing is 0.31nm. The output power reaches 6mW with the optical signal to noise ratio of greater than 30dB. A 12.5Gb/s codes rate is used in the fiber laser transmission experiment. A nice optical eye diagram is recieved after long distance single-mode communications fiber transmission.
