- Abstract: The polarization of optical fields is a crucial degree of freedom in the
all-optical analogue of electromagnetically induced transparency (EIT).
However, the physical origins of EIT and polarization induced phenomena have
not been well distinguished, which can lead to confusion in associated
applications such as slow light and optical/quantum storage. Here we study the
polarization effects in various optical EIT systems. We find that a
polarization mismatch between whispering gallery modes in two indirectly
coupled resonators can induce a narrow transparency window in the transmission
spectrum resembling the EIT lineshape. However, such polarization induced
transparency (PIT) is distinct from EIT: it originates from strong polarization
rotation effects and shows unidirectional feature. The coexistence of PIT and
EIT provides new routes for the manipulation of light flow in optical resonator
systems.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

The magnetic field changes the lineshape of the intersubband optical transition due to the roughness of the interface of the quantum well from a Lorentzian to a Gaussian one.

The resonant dipole-dipole interactions manifest in the cooperative spontaneous emission of the probe light transition.

electromagnetically induced transparency (EIT) is a narrow transparency window associated with a fluorescence quench at its center frequency.
