摘　　要：The switchable dual-wavelength erbium-doped fiber laser(EDFL) with a two-mode photonic crystal fiber(PCF) loop mirror and a chirped fiber Bragg grating(CFBG) at room temperature is proposed and experimentally demonstrated.The two-mode PCF loop mirror is formed by inserting a piece of two-mode PCF into a Sagnac loop mirror,with the air-holes of the PCF intentionally collapsing at the splices.By adjusting the state of the polarization controller(PC) appropriately,the laser can be switched between the stable single-and dual-wavelength operations by means of the polarization hole burning(PHB) and spectral hole burning(SHB) effects.The switchable dual-wavelength erbium-doped fiber laser （EDFL） with a two-mode photonic crystal fiber （PCF） loop mirror and a chirped fiber Bragg grating （CFBG） at room temperature is proposed and experimentally demonstrated. The two-mode PCF loop mirror is formed by inserting a piece of two-mode PCF into a Sagnac loop mirror, with the air-holes of the PCF intentionally collapsing at the splices. By adjusting the state of the polarization controller （PC） appropriately, the laser can be switched between the stable single- and dual-wavelength operations by means of the polarization hole burning （PHB） and spectral hole buming （SHB） effects.
