Multiwavelength pulse generation in semiconductor-fiber ring laser using a sampled fiber grating

Abstract

A novel multiwavelength scheme has been demonstrated using a sampled fiber grating in semiconductor-fiber ring laser. By using semiconductor optical amplifier as an inhomogeneously broadened gain medium, three wavelength channels of 10 GHz are simultaneously generated. The number of the lasing channels can be changed through the polarization state adjustment in the cavity. (C) 2001 Elsevier Science B.V. All rights reserved.
