“…Previously, various techniques to generate MW-ML-EDFL have been proposed [4][5][6][7][8]. Due to the homogeneously broadened gain property, many 2-or 4-wavelength EDFLs are developed with wavelength spacing larger than homogenous linewidth (~3.5 nm) to overcome gain competitions [3][4][5]. Although a MW-EDFL with 16 wavelengths has been presented by cooling an EDF to 77 K using liquid nitrogen [9], the increased complexity and cost make it impractical to many applications.…”

“…Compared with the compact, inhomogeneously gain broadened semiconductor-based multiwavelength laser source [2], EDFLs are competitive for the all-fiber structure and high pulse energy. Although the generation of mode-locked ultra-short pulses of an EDFL is well known, there exist great challenges to apply the ML-EDFL to multi-wavelength (MW) optical communications due to its stability and temporal-spectral properties [3]. Previously, various techniques to generate MW-ML-EDFL have been proposed [4][5][6][7][8].…”

In this paper, we demonstrate a novel stabilization scheme of actively harmonically mode-locked Erbium-doped fiber lasers (ML-EDFLs) by using highly nonlinear fibers in the cavity. 2 and 4 wavelengths anchored on ITU-T standards with 100 GHz channel spacing are successfully generated without gain competition. The amplitude fluctuation and timing jitter are measured to be less than 1% and 100fs, respectively.

“…[1][2][3][4][5][6] Currently most of these reported ring lasers use a continuouswavelength-tuning scheme. [2][3][4][5] However, for many test or measurement applications related to a WDM system, one prefers light sources that have selectable output wavelengths within specified channel wavelengths. Such a channel wavelength selectable laser was proposed by Liou and Koren, 1 which used a Fabry-Perot semiconductor optical amplifier as the gain medium, and an arrayed waveguide grating router ͑AWGR͒ as a channel wavelength selector.…”

Channel wavelength selectable single/dual-wavelength erbium-doped fiber ring laser

We present a new channel wavelength selectable single/ dual-wavelength erbium-doped fiber ring laser. The novelty of this device is the use of a specially designed fiber cascaded Mach-Zender interferometer (MZI) called a channel wavelength generator (CWG) that has a triangular-shaped transfer function. The lasing wavelength only occurs in the vicinity of the peak wavelengths of the transfer function of the MZI when tuning the filter, and this makes it channel wavelength selectable. With a compound cavity structure, gain balance between two different wavelengths is easily achieved by adjusting the overlapping positions of the passbands of the filters over the CWG pattern, and as a result two stable lasing wavelengths are achieved simultaneous. Each wavelength can be tuned individually. The deviation of the exact lasing wavelength from the desired channel wavelength is estimated to be less than 1/20 of the CWG's channel spacing (100 GHz). In addition, it is also observed that the use of the CWG reduces significantly the number of longitudinal modes, and hence improves the stability of the output power.

“…Dual-wavelength short pulses also find applications in the field of optical pump-probe measurement. Various techniques have been proposed to generate dual or multiple wavelength pulses from a harmonically mode-locked fiber laser in the last few years (Bakhshi et al 1999;Li and Chan 1999;Chen et al 2000;Lee and Shu 2000;Deparis et al 2001;Zhao et al 2001;Chan and Shu 2002;Lou et al 2002;Pudo et al 2002;Yang et al 2002;Pudo and Chen 2003). Fiber Bragg gratings (FBGs), on the other hand, are ideal wavelength selection components for fiber lasers due to the unique advantages of fiber compatibility, ease of use and low cost.…”

A simple actively mode-locked fiber ring laser is proposed and successfully demonstrated to generate dual-wavelength picosecond pulses with close wavelength spacing using one Bragg grating in standard single-mode fiber. The proposed laser can be made to operate in stable dual-wavelength at room temperature, due to the birefringence characteristic of the FBG induced by transverse strain. Transverse strain loading on the FBG allows the wavelength spacing to be controlled. Generation of stable dualwavelength pulses with a pulsewidth of 212-234 ps and a tunable wavelength separation from 0.2 to 0.44 nm at a pulse rate of 1.05 GHz was demonstrated.
