Summary: Optofluidic laser (OFL) technology, a combination of microfluidics and laser technology, has unique advantages in sensing applications and is a hot research topic for highly-sensitive intracavity biochemical analysis. OFL-based biochemical sensors can achieve high detection sensitivity by detecting changes in biochemical parameters through significant changes in laser output characteristics. This article provides an overview of OFLs, including their constructions, the design of OFL-based biochemical sensors, and their applications. The current challenges and future development directions of OFLs in the field of biochemical sensing are also briefly discussed.

Summary: We have developed a silica-based large mode area fiber with a nanostructured core for use in fiber laser cavities. Our experimental results demonstrate that the fiber operates in single mode with low bending loss. We have also successfully fabricated high reflectivity UV induced fiber Bragg gratings and utilized them in a fiber laser setup. The flexibility of the nanostructuring approach holds promise for the development of passive fiber components that can be matched with any type of active fibers.

Summary: Vortex beams with phase or polarization singularity in their center part have unique features and applications in fields such as optical communication and optical tweezer. Compared to traditional Gaussian beams, vortex beams offer more freedom in optical sensing by controlling spin, orbital phase, and polarization. This review discusses the theory of polarization and phase vortices, as well as the generation of vortex beams in optical fiber and their sensing applications, aiming to inspire further research and development in fiber vortex for sensing applications.

Summary: In the history, optical links have been served by light emitting devices and multimode glass fibers. However, with the demand for higher data rates and bandwidth density, vertical cavity surface emitting lasers (VCSELs) and coarse short-wavelength division multiplexing technology become necessary. By using multicore fiber and on-chip mini arrays of oxide-confined VCSELs, higher data rates and transmission distances can be achieved.

Summary: In this study, a novel method was proposed and demonstrated to achieve pulsed operation of thulium-doped fiber lasers at 1.7 μm. By embedding the thulium-doped fiber laser cavity within the cavity of an erbium/ytterbium-codoped fiber laser operating at 1.5 μm, the 1.5 μm laser was forced to operate in a passively Q-switched scheme using the thulium-doped fiber as a saturable absorber. The thulium-doped fiber laser at 1.7 μm was then pumped by the Q-switched 1.5 μm laser and gain-switched. The experimental results matched well with the theoretical model, providing insights for further improving the laser performance.

Summary: The research field of photonic crystals (PhCs) is active globally. PhCs, which are periodic optical nanostructures, have excellent light field confinement and numerous degrees of freedom, providing a solid foundation for controlling light movement. Devices based on PhCs, such as power splitters, modulators, polarization maintaining devices, sensors, and lasers, have been proposed and extensively used. These devices have superior performance and a smaller footprint compared to conventional photonic devices.

Summary: By passively combining sixty-one lasing fiber channels in a monolithic optical resonator array, researchers achieved an output power above 200W at a two-micrometer wavelength. The study found that the central intensity enhancement improves as the number of channels increases, which is an important step towards a passively combined multichannel all-solid-state laser system.

Summary: This paper proposes and demonstrates a novel single-frequency erbium-doped random distributed Bragg reflector fiber laser, constructed by a random fiber grating and a high-reflection fiber Bragg grating. The use of femtosecond laser point-by-point inscription technique for the random fiber grating enables easy and low-cost fabrication of long gratings. Experimental results show that the laser achieves stable single-peak emission and operates at a single frequency.
