Title: | Stable and uniform multiwavelength erbium-doped fiber laser using nonlinear polarization rotation | Authors: | Feng, X Tam, HY Wai, PKA |
Issue Date: | 4-Sep-2006 | Source: | Optics express, 4 Sept. 2006, v. 14, no. 18, p. 8205-8210 | Abstract: | A novel and simple technique, based on nonlinear polarization rotation (NPR) effect, to generate stable multiwavelength oscillations in an erbium-doped fiber laser is proposed and successfully demonstrated. The NPR effect effectively induced intensity- and wavelength-dependent loss to alleviate mode competition caused by homogeneous gain broadening in erbium-doped fibers. Up to 28-wavelength lasing operation with wavelength spacing of 0.8 nm has been achieved. The outputs had uniform power distributions, and the power fluctuation in each wavelength is smaller than 0.2 dB within a period of an hour. | Keywords: | Electric power distribution Erbium Oscillations Polarographic analysis Semiconductor doping |
