A tunable and switchable single-longitudinal-mode dual-wavelength fiber laser with a simple linear cavity

Abstract

A simple linear cavity erbium-doped fiber laser based on a Fabry-Perot filter which consists of a pair of fiber Bragg gratings is proposed for tunable and switchable single-longitudinal-mode dualwavelength operation. The single-longitudinal-mode is obtained by the saturable absorption of an unpumed erbium-doped fiber together with a narrow-band fiber Bragg grating. Under the high pump power (>166mW) condition, the stable dual-wavelength oscillation with uniform amplitude can be realized by carefully adjusting the polarization controller in the cavity. Wavelength selection and switching are achieved by tuning the narrow-band fiber Bragg grating in the system. The spacing of the dualwavelength can be selected at 0.20nm (~ 25.62GHz), 0.22nm (~ 28.19GHz) and 0.54nm (~ 69.19GHz). ©2009 Optical Society of AmericaOCIS codes: (000.0000) General; (000.2700) General science.

Carrier generation using a dual-frequency distributed feedback waveguide laser for phased array antenna (PAA)

“…In the past years, reports on microwave carrier generation by using a DFL were mainly focused on very low phase noise [48,49] or large tunability [15,50]. However, there seems to be very little attention to some crucial requirements of the generated carrier, namely its short term as well as long-term frequency stability.…”

“…Heterodyning of two optical frequencies coming from a single laser cavity has shown its potential on improvement of frequency stability [14]. In this regard a dual-frequency laser (DFL) is interesting as the relative fluctuations between the two frequencies are low and can be used to generate a low-phase-noise microwave carrier due to the common-mode noise rejection effect [13,[15][16][17].…”

A Novel Technique for Designing High Power Semiconductor Optical Amplifier (SOA)-Based Tunable Fiber Compound-Ring Lasers Using Low Power Optical Components

“…Single-mode fiber resonators of different architectures such as linear [1], Fox-Smith [2], ring [3][4][5], and compound fiber ring [6][7][8][9] cavities have been theoretically and experimentally explored in designing and building various kinds of fiber laser sources with single-longitudinal mode operation for low and high optical power applications such as optical communication systems, and for scientific, medical, material processing and military purposes [10]. Adjustable, scalable output optical power and wavelength tunability properties of a fiber laser source are of a great interest in the aforementioned applications that require high optical power.…”

A dual-pass Mach–Zehnder interferometer filter using a TCF loop mirror for double-wavelength fiber lasers

“…In order to obtain these properties, wavelength selective filters are very important components which can reduce the mode competition and suppress the mode hopping in the lasers cavity for EDFL. Until now, the main two kinds of optical filters have been proposed to achieve dual-wavelength EDFL [5][6][7][8][9][10][11][12], namely narrow band filters and comb filters. The narrow band filters are usually composed of the fiber Bragg gratings (FBGs) [5][6][7][8][9].…”
