| Outline of Final Research Achievements |
A non-mechanical beam scanner is one of key components for future LiDAR systems. In this study, we realized the high-power and high-resolution beam steering function of VCSEL amplifier scanner thanks to its angular dispersion and high gain amplifier function, exhibiting the number of resolution points of over 300 and an output power of over 0.4W. We also demonstrated a lateral integration platform of VCSEL amplifier and high-resolution beam scanner. In addition, the 2D beam scanning was demonstrated by using 1D VCSEL scanner array and a cylindrical lens, showing a number of resolution points of 270×7.
