Purcell factor and superradiance in Si-patterned waveguides.
Numerical modeling of slotted photonic crystal Si waveguides is reported. Employing multiple slots in a single waveguide, we obtained large Purcell enhancements for a large ensemble of emitters coupled with the same optical mode. This allows observation of peculiar physical phenomena, such as anisotropic bandgap superradiance.
