Apodized Slanted Grating Couplers for LiDAR Applications
arxiv(2024)
摘要
Solid state LiDAR systems traditionally rely on costly active components for
efficient beam scanning. In this study, we propose a cost-effective, purely
passive steering approach using apodized slanted grating couplers. Through
apodization, we achieve a uniform upward emission profile and enhanced upward
transmission. Theoretical calculations indicate successful steering of
91.5^∘x42.8^∘. Experimental results closely match theoretical
predictions, validating the capabilities of our passive steering concept.
Additionally, the grating couplers, with a length of 3mm, enable a farfield
FWHM of 0.026^∘, further enhancing sensing resolution.
