“…By using a dual-core all-solid bandgap PCF a switchable multi-wavelength erbium-doped fiber laser was fabricated [69]. A tunable and switchable multi-wavelength erbium-doped fiber laser was accomplished by incorporating a highly nonlinear PCF in the ring cavity [70]. With a twin-core PCF a multiwavelength erbium-doped fiber laser was accomplished [71].…”

A review on all-fiber lasers based on photonic crystal fibers is presented. Photonic crystal fibers present improved features beyond what conventional optical fibers can offer. Due to their geometric versatility, photonic crystal fibers can present special properties and abilities which can lead to enhanced lasing structures. A brief description of photonic crystal fibers and fiber laser's properties is presented. All-fiber laser structures developed using photonic crystal fibers are described and divided in two groups, depending on the cavity topology: ring cavity fiber lasers and linear cavity fiber lasers. All-fiber lasers applications in the photonic crystal fiber related sensing field are described.

“…Tn our previous report [12] , by inserting a length of highly nonlinear photonic crystal fiber(HNL-PCF) in the resonant cavity to induce the four-wave mixing(FWM) effect, a tunable and switchable multi-wavelength Er-doped photonic crystal fiber ring laser without any wavelength selection components can operate in dual-wavelength or triple-wavelength outputs. Tn the proposed laser configuration [12f , the use of an ED-PCF as the gain medium can provide high performance, and we improve our device to achieve better performance by substituting a polarization-dependent optical isolator (PD-ISO) for an ordinary isolator.…”

“…In order to realize multi-wavelength laser outputs, the suitable air hole size and hole pitch of the ED-PCF are designed for getting higher birefringence coefficient. The scanning electron micrograph of the cross-section of the ED PCF is shown in [12]. The ED-PCF with seven rings of air holes is fabricated by modified chemical vapor deposition (MCVD).…”

A multi-wavelength Erbium-doped photonic crystal fiber ring laser utilizing nonlinear polarization rotation was demonstrated by experiment. A polarization dependent isolator with a 9m Er-doped photonic crystal fiber was used to form an equivalent fiber filter. The fiber laser without specific wavelength selection device could operate at single-wavelength, dual-wavelength, triple wavelength and quadruple-wavelength depending on the polarization. The intensity-dependent inhomogeneous loss induced by nonlinear polarization rotation was applied to reduce the mode competition. Therefore, stable multi wavelength output with the power fluctuation of 0.27dB was generated at room temperature. In the meantime, the tuning of wavelength could be achieved through adjusting the polarization controller. The quadruple-wavelength with a spacing of 2.2 nm was achieved, and the uniformity of multi-wavelength spectra was improved by increasing pump power. The proposed fiber laser with an extinction ratio of higher than 40 dB achieved a low threshold power of about 30 mW to realize simultaneously multi wavelength outputs.

“…In most of these methods, the lasing wavelengths are switched by adjusting the polarization in the cavity, which is a complex optical technique and they have some obvious disadvantages. Another important aspect to take into account of the multi-wavelength erbium doped fiber laser (MEDFL) is their output power instability and mode competition [10]. These instabilities as well as a multi-longitudinal mode (MLM) operation can degrade the performance characteristics of a sensor array based on a tunable ring laser interrogation scheme.…”

Single-Longitudinal-Mode Dual Wavelength-Switchable Fiber Laser Based on Superposed Fiber Bragg Gratings

et al. 2015

In this work, a simple switchable dual-wavelength short-cavity fiber laser operating in a single-longitudinal-mode regime at room temperature and based on superposed fiber Bragg gratings is proposed and experimentally demonstrated. Only by introducing stress into one of the overwritten FBGs, single-or dual-wavelength laser oscillations can be attained. Either single-or multimode operation of the laser can be easily achieved. Single-longitudinal-mode emission has been verified in two different ways: the first corroboration has been conducted by the heterodyne detection of the output signal, and the second one has been carried out by using a high-resolution optical spectrum analyzer.
