Tunable multi-wavelength SOA based linear cavity dual-output port fiber laser using Lyot-Sagnac loop mirror

Abstract

We propose and demonstrate a simple dual port tunable from the C- to the L-band multi-wavelength fiber laser based on a SOA designed for C-band operation and fiber loop mirrors. The laser incorporates a polarization maintaining fiber in one of the fiber loop mirrors and delivers multi-wavelength operation at 9 laser lines with a wavelength separation of ~2.8 nm at room temperature. We show that the number of lasing wavelengths increases with the increase of the bias current of the SOA. Wavelength tunability from the C to L-band is achieved by exploiting the gain compression of a SOA. Stable multi-wavelength operation is achieved at room temperature without temperature compensation techniques, with measured power and the wavelength stability within < ±0.5 dB and ±0.1 nm, respectively.

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

“…In addition, the single-mode performance is maintained in order to improve the brightness at the proposed fiber compound-ring laser output port. The output power of the proposed combined fiber compound-ring resonators with two low power SOAs was almost twice as large as the output power obtained from a single SOA-based fiber ring or the Fabry-Perot linear resonator [25]. More than 98% beam combining efficiency of two parallel nested fiber ring resonators is demonstrated over the C-band tuning range of 30 nm.…”

“…All-single-mode fiber-based Sagnac loop mirrors have been widely used in temperature [18], strain [19], and pressure [20] high sensitivity sensors as well as in wavelength optical switches [21]. Moreover, SLMs with adjustable reflectivity have been used to form Fabry-Perot linear resonators [22][23][24][25] where the amount of the output optical power from the resonators depends on the reflectivity of the SLMs [26,27]. In this work, two SLMs were used to control the amount of optical power delivered from two output ports of the proposed fiber compound-ring laser.…”

Stable optical clock generation in SOA-based fiber lasers with figure-eight cavity

“…Recently, semiconductor optical amplifiers (SOAs) have been used as the gain media of fiber lasers [1][2][3]. As compared with the rare-earth-doped fibers, SOAs have many advantages such as electrical pumping, high optical nonlinearity, rapid tunability, and large gain bandwidth.…”

Switchable wavelength generation by injection-locked fiber laser based on GS-RSOAs

“…Other studies on optical fiber amplification using SOAs include an SOA linear cavity optical fiber laser using a Sagnac and Lyot Sagnac loop mirror and an SOA [15], and an SOA optical fiber laser using an SOA and broadband FBG [16]. With merits such as com pact size, low power consumption, and short term stability, SOAs can be directly modulated at a high bitrates by using optical injections.…”
