Cascaded Mode Interferometers
We present a novel framework that uses the interference of multiple transverse modes in a single multimode waveguide to achieve arbitrary spectral shapes in a compact geometry. We theoretically and experimentally demonstrate narrow-linewidth spectra with independently tunable free spectral range and linewidth and independent spectral shapes.
