Query: Polarization-Controlled Cavity Input-Output Relations   Cavity input-output relations (CIORs) describe a universal formalism relating
each of the far-field amplitudes outside the cavity to the internal cavity
fields. Conventionally, they are derived based on a weak-scattering
approximation. In this context, the amplitude of the off-resonant field remains
nearly unaffected by the cavity, with the high coupling efficiency into cavity
modes being attributed to destructive interference between the transmitted (or
reflected) field and the output field from the cavity. In this Letter, we show
that, in a whispering gallery resonator-waveguide coupled system, in the
strong-scattering regime, the off-resonant field approaches to zero, but more
than 90% coupling efficiency can still be achieved due to the Purcell-enhanced
channeling. As a result, the CIORs turn out to be essentially different than in
the weak-scattering regime. With this fact, we propose that the CIOR can be
tailored by controlling the scattering strength. This is experimentally
demonstrated by the transmission spectra exhibiting either bandstop or
bandpass-type behavior according to the polarization of the input light field.
