“…Ahmed et al presented a stable multiwavelength EDFL by means of the phase modulator in a linear cavity configuration. The stable multiwavelength lasing was achieved by applying any one of the waveforms of sine, square, saw-toothed, and triangular at a suitable frequency between 500 Hz to a few tens of kHz to the phase modulator [13]. Sun introduced self-lasing feedback in conventional phase-modulation-based multiwavelength fiber ring lasers, in which the number of lasing lines was increased and the differences among the lasing lines were diminished [14].…”

Abstract:We propose and demonstrate a tunable multiwavelength erbium-doped fiber laser based on a polarizationmaintaining photonic crystal fiber (PM-PCF) Sagnac loop filter. Stable, room-temperature operation is obtained by employing a nonlinear optical loop mirror. At a central wavelength of 1563.000 nm, we generate 60 wavelengths within 3-dB bandwidth. The measured power fluctuation for each lasing wavelength is less than 0.2 dB in half an hour. Furthermore, by adjusting the polarization controllers in the Sagnac filter, wavelength locations of the laser lines with a fixed channel spacing of ∼ 0.078 nm can be continuously shifted.Intensity, 2 dB/div 1562.6

We have experimentally investigated a stably tunable multiwavelength erbium-doped fiber ring laser based on phase modulation of a semiconductor optical amplifier with lasing wavelength and spacing tunability at room temperature. Stable multiwavelength operation is obtained by direct modulation of the bias current in the amplifier. We demonstrate such a laser incorporating a tunable Lyot-Sagnac filter with two segments of polarization-maintaining fibers with wavelength-spacing and lasing wavelength tunability. We successfully achieved 1.0-nm-spacing eight-channel and 0.8-nm-spacing ten-channel lasing wavelengths at room temperature. The lasing wavelength of the laser can be also controlled by a polarization controller.
