Tran Thi Tam, Vu Ngoc Cham, Dang Quoc Trung, Tran Anh Vu, Le Huu Minh


The linear configuration single-mode Distributed Bragg Reflection (DBR) Erbium doped Fiber laser has been tested. The cavity length of the laser utilizing intracore Bragg reflectors, no longer than one centimetre and the grating bandwidth is below ~ 0.2 nm. The 1.55-$\mu$m emission wavelength of the laser can be continously tuned within 2 nm.
