“…LCM and microlens array have been widely used in switchable displays, [ 118 ] beam shaping, [ 79 ] wavefront sensing, [ 142 ] and optical interconnects. [ 143 ] Due to the relentless drive in the photonic system to realize compact, wearable, miniaturized, and integrated devices over the past decade, LCMs have become more and more popular. The advantages, such as electric tunability, small foot of print, low weight, cost‐effectiveness, and ease to produce in pack, have made LCMs promising candidates for a wide range of applications.…”

Microlenses and microlens arrays are one of the indispensable components in modern optical systems ranging from imaging and beam shaping to polarization control and switchable 2D/3D displays. Among them, the liquid crystal microlenses (LCMs) with size below 1 mm have attracted more and more attention due to their stimuli‐responsiveness and tunability in focal length and polarization. Compared with microlenses based on inorganic binary optics, diffractive optical elements, or metasurface, LCMs are more cost‐effective and can be easily tuned. In this paper, an in‐depth review of the design principles, fabrication techniques, emerging applications, and recent advances of LCMs and arrays is presented, aiming to clarify the characteristics, limitations, and challenges in LCMs design and fabrication. This review may provide directions for solving those challenges, and expand the applications of LCMs.

Based on the simplified model of the tunable fiber laser system, the tuning performance of the laser was analyzed. Two kinds of tunable setups were established, which are the configurations with an external cavity and the configuration of the Littrow cavity. The tuning output characteristics experimentally were analyzed by means of setups. The simulation gives the output efficiency of two tunable lasers as 40% and 30%. In the experiment, the measured slope efficiency of the two lasers was 24% and 18.3%, and the tunable range of the two lasers was 32 nm and 40 nm, respectively. Both lasers could achieve laser output with good beam quality.
