Fano resonance lineshapes in a waveguide-microring structure enabled by an air-hole
We propose and demonstrate, by simply inserting an air-hole in the waveguide side-coupling with a microring resonator (MRR), that the transmission spectrum presents Fano lineshapes at all of the resonant modes. Measured from the fabricated devices, Fano lineshapes with slope rates over 400 dB/nm and...
