On-Chip Lasers on Waveguides: A Meta-Morphosis in Waveguide Imaging!
Paper in proceeding, 2025
Scattering-based microscopy with an evanescent field enhances signal-to-noise by suppressing background. Waveguides generate evanescent waves, but edge-coupling of light is difficult to use. Bonding a VCSEL to a waveguide platform enables an easy coupling via a grating coupler. Integrating a metasurface into the VCSEL tilts emission, improving waveguide excitation.
