    Abstract: Based on combining of Photonic Crystal Fiber (PCF) and Tapered Optical Fiber (TOF) at room
temperature, a dual-wavelength Erbium Doped Fiber (EDF) laser has been proposed and demonstrated. The TOF
is fabricated by using fully computerized tapered optical fiber fabrication system. The experimental results
showed that the generated dual-wavelength laser at low pumping power of 28.86 mW is highly stable. In
addition, single wavelength fiber laser can also be achieved by only the reduction of the input power.
