legume.HopfieldPol

class legume.HopfieldPol(phc, gmax, truncate_g='abs')

Main simulation class of the generalized Hopfield matrix method.

__init__(phc, gmax, truncate_g='abs')

Initialize the Schroedinger equation expansion.

Parameters:

• phc (PhotCryst) – Photonic crystal object to be simulated.

• gmax (float, optional) – Maximum reciprocal lattice wave-vector length in units of 2pi/a.

• truncate_g ({'tbt', 'abs'}) – Truncation of the reciprocal lattice vectors, 'tbt' takes a parallelogram in reciprocal space, while 'abs' takes a circle.

Methods

__init__(phc, gmax[, truncate_g])	Initialize the Schroedinger equation expansion.
run([gme_options, exc_options, kpoints, verbose])	Compute the eigenmodes of the photonic crystal taking into account light-matter interaction.

Attributes

eners	Energies of the eigenmodes computed by the Hopfield matrix diagonalisation.
eners_im	Imaginary part of the frequencies of the eigenmodes computed by the Hopfield matrix diagonalisation.
fractions_ex	Excitonic fractions of the polaritonic eigenmodes.
fractions_ph	Photonic fractions of the polaritonic eigenmodes.
gvec	Numpy array of shape (2, Ng) with the [gx, gy] coordinates of the reciprocal lattice vectors over which the simulation is run.
kpoints	Numpy array of shape (2, Nk) with the [kx, ky] coordinates of the k-vectors over which the simulation is run.
