Conventional semiconductor lasers, such as distributed feedback (DFB) lasers, can achieve narrow linewidths but are limited in power output. On the other hand, high-power lasers tend to suffer from broad linewidths due to multimode operation and thermal effects. Narrow-linewidth lasers often rely on external optical feedback systems to reduce frequency range to the kHz or sub-kHz range to increase its precision. While effective, these systems add complexity and cost, requiring precise optical alignment. When the cavity size of conventional semiconductor lasers is increased, multimode lasing typically occurs, which broadens the frequency range and lowers precision as the power output rises. As a result, high-power, narrow frequency range lasers face challenges in scalability due to issues like thermal effects, multimode operation, or the reliance on external stabilization systems. The technology owner have developed a photonic-crystal surface-emitting lasers (PCSELs) for optical systems that provides high power output (up to 10W) with narrow intrinsic linewidths (~1 kHz), a performance that conventional semiconductor lasers cannot achieve without external stabilization systems.

Crystal structure includes distributed Bragg reflectors (DBRs), which enhances vertical emission by reflecting downward-emitted light back upward. Enables large-area single-mode lasing (1mm in diameter) which is larger than conventional semiconductor lasers while maintaining single-mode operation. Have a narrow intrinsic spectral linewidth (1 kHz) without external feedback systems, ideal for applications requiring stable, narrow-linewidth light sources Reduces thermal non-uniformity via a current density adjustment, preventing linewidth broadening due to temperature-induced refractive index changes High-power delivery (up to 10W) of continuous-wave (CW) output while maintaining a narrow linewidth, a significant advancement over conventional lasers which typically sacrifice linewidth for higher power Due to the high brightness, high power, and narrow linewidth of any optical systems utilising PCSELs, it can be used for the following applications: Industrial machinery utilising lasers (e.g. machining) Material treatment utilising lasers for surface modification (e.g. semiconductor equipment) Long-distance free-space optical communications Light detection and ranging applications with potential spaceborne use-case (e.g. LiDAR) PCSELs tackles the challenges faced by existing conventional semiconductor lasers by introducing a double-lattice photonic crystal design with distributed Bragg reflectors (DBRs) to deliver a high power and high precision without external feedback via its intrinsic narrow linewidth.
