“…Due to their controllable energy band-gap, strong electron mobility, improved exaction-binding energies throughout quantum wells (QW), as well as much lower appearance of piezoelectric (PZ) regions and associated quantum confinement stark effect (QCSE), III-V semiconductor zinc blende (ZB) trio but instead alloys containing quaternary elements were used thoroughly for higher efficiency applications in optoelectronics such as laser diodes and LED along with for electronic mode of transportation [1]. Near-infrared (NIR) lasers with an active area formed of III(Al,Ga,In)-V(P,As,Sb,N) ZB composite alloys but also oscillating at around 1.50 ~ 2.00 µm wavelength have piqued interest because of their wide range of applications throughout healthcare science (eye surgery), LIDAR (light detection and ranging), gas (CO2/NOx) suspecting, optical communications, hyper-spectral image analysis, and security [2][3][4]. According to recent research, 2.0 µm laser emission is beneficial for accurate surgery in Urology, Gynecology, and Neurology [5,6].…”

The optoelectronic achievement of a lattice matching InGaAs/InP lateral cavity surface radiating LASER in crystal orientations (100), (110), (111), (113), and (131) is computationally simulated utilising MATLAB by attempting to solve a k.p Hamiltonian of eight-band utilising only a finite difference strategy with spin-orbit linkage. To shift wave-vector k as well as Hamiltonian from traditional (100) plane orientation, tensor plane revolution equations are used. It is demonstrated that optical emission spectrum and crystal plane alignments have a significant correlation. At a carriers injection density of 2.50 x 1018 per cm3, the maximum and minimum gains are measured in the (111) as well as (100) orientations, respectively, with optimum emission wavelengths of 1770.00nm and 1680.00nm. This research will serve as a catalyst for the development of ultra-fast optoelectronic devices with improved performance thanks to the use of non-100 orientation epitaxial layers.

“…The wide lasing range (1700-2100 nm) [1] of TDF emitting at a 2 μm wavelength band makes the TDFL a potential light source in optical communication systems [2][3][4]. The characteristic of being readily absorbed by certain gas molecules facilitates the application of the TDFL in sensing gases, such as hydrocarbon gas [5] and CO2 [6]. In addition, the lasing wavelength at this waveband can be highly absorbed by water, which leads to substantial heating in small areas of biological tissue.…”

In this article, a precisely controlled, switchable thulium-doped fiber laser (TDFL) with high optical signal-to-noise ratio (OSNR) is proposed and demonstrated. A home-made multimode fiber Bragg grating (MMFBG) with multireflection peaks was used as an optical filter to select the desired lasing channel. Using a manually controlled fusion splicer, the axial misalignment was applied between the single mode fiber and the MMFBG to switch the output wavelength. In the experiment, the number of switchable lasing lines was up to 12, and the fluctuation of the center wavelength and output power was less than 0.03 nm and 0.67 dB, respectively. A maximum slope efficiency of 1.3% was obtained when the axial misalignment was 0 μm, and the OSNR was higher than 65 dB. In addition, the proposed fiber laser was used as an optical fiber laser sensor to quantify the strain applied on the MMFBG, and a sensitivity of 1.16 pm/με was obtained.

“…This property is much needed in free-space optical communication system 18 or in LIDAR (Light Detection and Ranging) [19][20][21] . Additionally, 2.0 µm laser sources play a critical role in the near-infrared (IR) gas spectroscopy and sensing owing to the e cient light absorption of atmospheric gaseous (e.g., carbon dioxide, CO 2 ) at 2.0 µm wavelength range [22][23][24] . 2.0 µm ber laser source can be generated from thulium-doped 25 and thulium/holmium-doped ber lasers 26 .…”

As a result of the emergence of two-dimensional (2D) materials for various opto-electronics applications, a new class of materials named MXenes have been attracting interests due to their outstanding nonlinear properties. In this work, an MXene niobium carbide (Nb2C) was proposed and demonstrated as a saturable absorber to induce mode-locking in thulium- and thulium/holmium-doped fiber lasers. The Nb2C solution was first prepared using the liquid exfoliation technique, and then deposited onto a microfiber for integration into the laser cavity. Stable mode-locking operation was observed in both laser cavities, where the center wavelengths of the laser were recorded at 1944 nm for the TDFL and 1950 nm for the THDFL. The generated pulses in the TDFL and THDFL had repetition rates of 9.35 and 11.76 MHz respectively, while their corresponding pulse widths were 1.67 and 1.34 ps. Both of the lasers were highly stable, having SNR values of more than 52 dB and showed no major fluctuations when tested for their long-term stabilities. The results demonstrate an excellent performance of the Nb2C as a saturable absorber, offering opportunities to further explore MXenes for future photonics devices.
