“…These implanted regions act as current-blocking regions, limiting the flow of current to the desired active region. Ion implantation enables precise control of the current confinement area and can be integrated with other fabrication steps [33]. By designing the implantation and array parameters, Pan et al obtained in-phase mode in arrays defined by large-scale proton implantation with metal grids [34].…”

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.

We report on a novel high power vertical cavity surface emitting laser (VCSEL) with high order shallow surface grating, which enables a single mode operation even for 6 mm long devices. A high single mode power of over 3 W is obtained under pulsed operations for a 6 mm long oxide aperture. A fan-shape beam with sub-degree narrow divergence is obtained up to high injection currents of 5 A. Thanks to the low effective index of slow-light modes in a VCSEL structure, the grating pitch is over 2.5 μm, which can be made by using a standard photo-lithography. The simple fabrication process and potentials of high power and high beam quality could make the proposed laser to be a good candidate for 3D optical sensing and imaging applications.
