Vertical-cavity surface emitting lasers (VCSELs) have emerged as a highly promising light source with extensive applications in various fields, including consumer electronics, optical communication, metrology, sensing and ranging. Their low-cost, high conversion efficiency, and compact footprint make them particularly attractive for widespread adoption. While considerable success has been made in enhancing the performance and speed of VCSELs for optical communications, achieving high-power VCSELs with properties such as high output power, single transverse mode operation, and temperature stability for remote sensing applications remains a challenging endeavor. This review aims to provide a comprehensive overview of the recent advancements in the development of high-power VCSELs. By examining the advancements in active materials, device designs, array configurations, this review seeks to shed light on the current state-of-the-art and potential avenues for further improvement in high-power VCSEL technology.

In this work, we propose a design method of an aspheric lens that achieves collimation for a VCSEL laser beam. The designed lens features a planar front surface and an aspheric back surface of which the profile is mathematically characterized and precisely determined based on the proposed method. The method is derived from a basic geometric-optics analysis and construction approach. The collimating effect of the lens was first analyzed in simulation and then validated in experimental measurement. The experimental results show that the collimator lens transforms the input VCSEL laser beam divergence angle from 25° (436.33 mrad) to an output angle of 3.6906 mrad.
