“…Although the use of nonlinear effects has attracted a lot of research interest in this area [1], [2], it is significantly simpler to produce a multiwavelength source using a single gain medium in combination with wavelength-selective elements. In order to select specific multiple lasing wavelengths, a wavelength-selective comb filter is typically included in the laser cavity [3]- [5].…”

An all-fiber comb filter using a tapered-erbium-doped fiber in a Mach-Zehnder interferometer structure is presented. The free spectral range, extinction ratio, bandwidth, and interference pattern of the comb filter can be shaped by controlling the taper waist length and the length of up and down taper transition regions. By varying the taper waist length from 5 to 25 mm, the free spectral range changes from 14.7 to 1.0 nm, and the linewidth varies from 3.3 to 0.3 nm, respectively. We demonstrate a tunable dualwavelength laser by using the tapered-erbium-doped fiber as a gain medium as well as a wavelength-selective element. The laser can be tuned at a resolution of 0.2 nm with a side-mode suppression ratio of up to 46.88 dB and a linewidth of 0.09 nm.

This investigation demonstrates a fiber-optical cable television system using a reflective semiconductor optical amplifier (RSOA) for uplink transmission. The downstream signal is cable television and the upstream signal is generated by remodulating the downstream signal via an RSOA with a radio-frequency signal. Favorable carrier-to-noise ratio, composite second-order, and composite triple beat are obtained for the downstream and the upstream signal is successfully transmitted over 60 km of single-mode fiber.

“…Multi-wavelength laser are attractive for use in optical code division multiple access networks and wavelength division multiplexed communication systems, owing to their ability to generate a large number of wavelength channels, thus eliminating the need for numerous wavelength-specific light sources and significantly reducing costs during the implementation and operation of communication systems and related networks [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Because of the homogeneous gain broadening characteristic of an erbium ion, achieving stable multi-wavelength oscillations is difficult in an erbium-doped fiber laser.…”

This work demonstrates the feasibility of a simple construct of a tunable triple-wavelength fiber ring laser using a Fabry-Perot laser diode (FP-LD) and an optical tunable bandpass filter. An optical tunable bandpass filter is used within the cavity of an erbium-doped fiber laser to select the lasing wavelength. Because the Fabry-Perot laser diode is in combination with the tunable bandpass filter, the erbium-doped fiber laser can stably lase three wavelengths simultaneously. Moreover, this laser is easily tuned dynamically. This triple-wavelength output performs satisfactorily, with its optical side-mode-suppression-ratio (SMSR) exceeding 40 dB. Furthermore, the wavelength tuning range of this triple-wavelength erbium-doped fiber laser is greater than 27 nm.
