Integrated optical microdisk-resonator,
2D simulations of configurations with the following specification: background refractive index n = 1.0,
refractive index of the guiding regions _{b}n = 1.5,
waveguide core width _{g}w = 0.4 µm,
cavity radius R = 5.0 µm,
gap g = 0.2 µm.
All calculations are meant for TE polarization, i.e. E
is the single nonvanishing component of the electrical field.

**Power transmission and drop spectrum:**

The resonator is excited in the lower left port by the guided mode of the
lower core.

*Caution:*
For the application of the QUEP programs, the structure has been represented
as a sequence of 200 z-homogeneous slices, or as a stack of 204 x-homogeneous
layers, that define a staircase approximation to the disk border. The spectral
discretization includes 120 modal terms per layer and slice on a square
interior computational window [-10, 10]x[-10, 10] µm^{2}.
Reflections, leading to partly standing waves inside the cavity (pronounced ripples in the plots of the field modulus), might thus well be pure numerical
artifacts.
