A chain of square dielectric optical microresonators

2D simulations of configurations with the following specification: background refractive index 1.45, refractive index of the guiding regions 3.4, waveguide core width 0.073 µm, cavity width / height 1.451 µm, all horizontal / vertical gaps 0.4 µm.

All calculations are meant for TE polarization, i.e. *E _{y}*
is the single nonvanishing component of the electrical field.
The QUEP simulations are based on a spectral discretization
with 110 modal terms per vertical slice, and 200 modal terms on each horizontal
layer, on an interior computational window [-3, 8.153]x[-3, 16.03] µm

Spectral properties

The resonator chain is exicted by the guided mode of the narrow
vertical channel, incoming from the top.
*R* and
*T*
are the guided power fractions that are reflected back into the input port
and transmitted straight through to the lower output channel, here functions
of the vacuum wavelength.
