    An actively mode-locked fiber ring laser for generating wavelength-tunable optical pulses is demonstrated. An Er-Yb doped waveguide amplifier is used as an optical amplifier, and a Fabry-Perot laser diode is used as a modulator in the fiber laser. Moreover, we add a variable optical delay line to control the cavity length for maintaining a constant repetition frequency and pulsewidth at different wavelengths. The optical side-mode-suppression-ratio is better than 33.5 dB over the wavelength-tunable range of 46 nm.

    A tunable dual-wavelength erbium-doped fiber ring laser using a self-seeded Fabry-Perot laser diode (FP-LD) is proposed and demonstrated. By adding an FP-LD incorporated with a tunable bandpass filter within the ring cavity, the fiber laser can lase two wavelengths simultaneously because of the self-seeded mechanism. This dual-wavelength output exhibits a good performance having the optical side-mode suppression ratio over 31 dB. The wavelength-tuning range of this tunable dual-wavelength fiber laser can be up to 9 nm.

    In this paper, we propose and demonstrate a tunable dual-wavelength fiber laser by using an external injection-seeding scheme with a Fabry-Perot laser diode. The wavelength tuning range of this tunable dual-wavelength fiber laser is 12.6 nm, and the optical side-mode suppression ratio (SMSR) is more than 27 dB. (C) 2004 Wiley Periodicals, Inc.

    A wavelength-tunable mode-locked linear-cavity fiber laser was demonstrated using a Fabry-Perot laser diode. By adding a tunable bandpass filter within the linear cavity, the wavelength-tunable fiber laser was easy to be tuned dynamically. This linear-cavity fiber laser output exhibited a good performance having the optical sidemode suppression ratio over 30 dB and the wavelength-tuning range up to 27 nm. Furthermore, this fiber laser generated pulses with pulsewidth between 53.2 and 80.4 ps at a repetition frequency of 908.39 MHz.

    An actively mode-locked fiber ring laser for generating wavelength-switched optical pulses is demonstrated in this paper. A Fabry-Perot laser diode (FP-LD) is used as a modulator, and a tunable filter is used as a wavelength selector. At a fixed modulation frequency, the optical side-mode-suppression-ratio (SMSR) of this fiber laser is better than 40dB over the wavelength-switched range of 31 nm. The pulsewidth is between 41.72 ps and 44.74 ps.

    We demonstrate tunable single- and dual-wavelength fiber ring lasers using a compact Er-Yb doped waveguide amplifier. In the single-wavelength operation, a signal-to-noise ratio higher than 63 dB and an output power maintaining around 11 dBm in the operation range over 50 nm (from 1529.1 to 1579.43 nm) are achieved. In the dual-wavelength operation, lasing wavelengths with wavelength separation from 51.73 to 6.2 nm are demonstrated. (c) 2005 Society of Photo-Optical Instrumentation Engineers.
