Abstract
Fano resonance has an asymmetric and sharp resonance peak near the
resonance wavelength, enhancing optical modulation performance. Here,
a Fano resonant silicon optical modulator with a micro-ring resonator
(MRR) coupled with a T-shaped waveguide is designed. Compared with an
MRR modulator, a Fano resonance-based modulator has a smaller
wavelength range of changes in optical intensity (from 0 a.u.
to 1 a.u.). Under the condition of achieving the same light
intensity change, Fano resonance only needs to shift the wavelength by
0.07 times compared with MRR. By optimizing the doping section and the
Fano resonance line shape, the modulation depth of the Fano modulator
is 12.44 dB, and an insertion loss of 0.41 dB is
obtained. Moreover, it improves the modulation linearity. This
modulator provides a new idea, to the best of our knowledge, for the
single-cavity Fano resonance modulator.
