“…However, amplifiers and lasers based on erbium-doped fiber (EDF) face a limitation due to strong mode competition in closely spaced wavelengths caused by the homogeneously broadened linewidth of EDF [7]. A laser cavity might be modified to incorporate nonlinear effects such as nonlinear polarization rotation (NPR) [8], four-wave mixing, or nonlinear amplifier loop mirror to further reduce wavelength competition and provide high-stability dual-wavelength operating in an EDFL. However, achieving the desired nonlinear effect poses challenges and necessitates a lengthy nonlinear fiber medium within the EDFL cavity, potentially impeding lasing realization.…”

A spacing-adjustable and switchable multi-wavelength erbium-doped fiber laser is proposed and analyzed based on the polarization hole burning (PHB) effect. The comb filter consists of multimode fiber - polarization maintaining fiber - multimode fiber (MMF-PMF-MMF). Here the filter is used as the polarization-dependent element to induce the polarization hole burning (PHB) effect. The filter is placed in the laser cavity or embedded into the Sagnac loop. By adjusting the polarization controller (PC) in the cavity, when the filter is placed in the laser cavity, the output wavelengths can be switched from single-wavelength to sextuple-wavelength, and dual-, triple-, quad-, quintuple- and sextuple-wavelength with adjustable wavelength spacing can be obtained. The dual-wavelength has a substantial amount of wavelength spacing adjustability with the range of 3.32 nm to 30.16 nm. When the filter is embedded into the Sagnac loop, the wavelength tuning ranges for single-, dual-, triple- and quad-wavelength are 28.42 nm, 28.10 nm, 18.21 nm and 14.58 nm, respectively. The proposed erbium-doped fiber laser (EDFL) provides a wide range of wavelengths and adjustable spacing, which is suitable for a variety of applications such as optical communication, optical detection and optical signal processing.

“…A semi-open laser cavity is created by using a circular mirror, and typical random laser radiation is produced [15]. A switchable multiwavelength optic laser with two elliptical structures as well as a core offset splicing junction was described by Chang et al in a mixed-structure fiber filter [16]. Later on, the research group also made improvements to and suggested an adjustable multiwavelength optic laser based on a hybrid cascaded optic filter made up of one single ellipsoidal hybrid optic filter and a Sagnac ring interferometer [17].…”

Compared with other lasers, fiber laser is widely used in optic communication, industrial production, biomedical sciences, and other fields because of its excellent technical performance, low manufacturing cost, mature technology, high conversion efficiency, high stability, and many other advantages. Recently, two new optical fiber communication techniques that are quickly evolving are Wavelength Division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM). As a result, multiwavelength and wavelength-tunable fiber lasers were created to address the demand for optical communication systems with high throughput, high quality, and high speed. Due to their advantages in lowering equipment complexity, enhancing network flexibility, enhancing fiber system integration, etc., switching dual-wavelength fiber lasers based on Array Waveguide Grating (AWG) have received a lot of attention. This paper studies two switching dual-wavelength fiber laser based on AWG. Firstly, the basic structure of Erbium-doped Fiber Laser (EDFL) is analyzed based on the basic principle of Erbium-Doped Fiber (EDF). In addition, the working principle of AWG is analyzed emphatically. Finally, AWG-based switching dual-wavelength fiber lasers in linear/ring cavity, which achieve that the adjustable wavelength intervals between 0.8nm to 12nm, are verified and discussed experimentally. Additionally, experimental data shows that the dual-wavelength lasing power is stable and equal.

Colloidal semiconductor quantum dots (QDs) can be considered a promising material platform for solution-processed laser diodes. However, due to some fundamental challenges, the realization of electrically pumped lasing based on QDs remains unresolved. Here, a binary blend of QDs and ZnO nanocrystals is employed, which serve as nano-sized scatterers to facilitate waveguide gain in ultra-thin films. By carefully engineering the electric field in these films, an infrared amplified spontaneous emission in a record thin colloidal gain medium is observed, with a thickness of 16 nm, at a wavelength of 1675 nm. Employing these binary blends as a gain medium, an optically pumped infrared stimulated emission in a full-stacked light-emitting diode (LED) device is demonstrated. The functional LED device, which comprises a single layer of graphene as an anode electrode, shows strong electroluminescence under electrical injection. This study suggests a promising device for realizing infrared QD-based laser diodes.
