High extinction tuneable filters at visible wavelengths
Integrated tuneable wavelength filters with high extinction and narrow lineshapes commonly underpin photonic chip architectures at infrared wavelengths, but are notably less mature at visible wavelengths. We address this, with high extinction (23 dB), narrow linewidth (1 pm) resonances achieved using cascaded tuneable SiN racetracks.
