Abstract

This paper describes the design of an all-fibre multiwavelength erbium doped fibre laser operating at room temperature.By using a Sagnac loop filter, multiple wavelength channels are obtained with 0.8nm spacing in the C-band and simultaneous multiwavelength operation is achieved through an intracavity sinusoidal phase modulator. A polarization controller inside the filter is helpful in controlling the multiwavelength operation. The effects of modulation frequency,modulation index and pump power on the multiwavelength operation are experimentally investigated. The fibre laser has potential applications in fibre Bragg grating sensors and fibre optic spectroscopy.
