  A photonic molecule (PM) is a miniature diffractive optical structure
composed of resonance microcavities called atoms (e.g., cylinders or spheres)
supporting a set of high-quality eigenmodes. All atoms in a PM are coupled by
the electromagnetic fields of eigenmodes, which form collective supermodes of
the whole PM. We consider a particular type of mirror-symmetric PMs being
optically excited simultaneously via two light channels (tapered fibers). Based
on the numerical simulations, we show that the spectral composition of
supermodes in such PM can be effectively manipulated by changing the phase
detuning between the optical channels. For a seven-atom silicon microcylinder
cyclic-PM is demonstrated the possibility to achieve tenfold intensity
amplification/suppression of several supermodes from the Stokes and anti-Stokes
bands of PM spectrum.
