RefractiveIndexProviderCyl Class

class plask.flow.RefractiveIndexProviderCyl(data)

Provider of the refractive index in Cylindrical geometry (-).

This class is used for refractive index provider in binary solvers. You can also create a custom provider for your Python solver.

Parameters:

data – Data object to interpolate or callable returning it for given mesh. The callable must accept the same arguments as the provider __call__ method (see below). It must also be able to give its length (i.e. have the __len__ method defined) that gives the number of different provided values.

To obtain the value from the provider simply call it. The call signature is as follows:

solver.outRefractiveIndex(comp, mesh, lam=DEFAULT, interpolation='default')
Parameters:

  • comp (str) – Component of a diagonal refractive index derivative to return. Can be ‘ll’, ‘tt’, ‘vv’, or equivalent using current axes names. For scalar solvers this argument is ignored and can be skipped.

  • mesh (mesh) – Target mesh to get the field at.

  • interpolation (str) – Requested interpolation method.

  • lam (float) – Complex wavelength at which the refractive index is computed (nm).

Returns:

Data with the refractive index on the specified mesh (-).

You may obtain the number of different values this provider can return by testing its length.

Example

Connect the provider to a receiver in some other solver:

>>> other_solver.inRefractiveIndex = solver.outRefractiveIndex

Obtain the provided field:

>>> solver.outRefractiveIndex(0, mesh, lam=DEFAULT)
<plask.Data at 0x1234567>

Test the number of provided values:

>>> len(solver.outRefractiveIndex)
3

Methods

__call__(...)

Get value from the provider.

set_changed()

Inform all connected receivers that the provided value has changed.

RefractiveIndexProviderCyl.__call__(comp, mesh, interpolation='DEFAULT')
RefractiveIndexProviderCyl.__call__(comp, mesh, lam, interpolation='DEFAULT')
RefractiveIndexProviderCyl.__call__(mesh, lam, interpolation='DEFAULT')
RefractiveIndexProviderCyl.__call__(mesh, interpolation='DEFAULT')

Get value from the provider.

Parameters:

  • comp (str) – Component of a diagonal refractive index derivative to return. Can be ‘ll’, ‘tt’, ‘vv’, or equivalent using current axes names. For scalar solvers this argument is ignored and can be skipped.

  • mesh (mesh) – Target mesh to get the field at.

  • interpolation (str) – Requested interpolation method.

  • lam (float) – Complex wavelength at which the refractive index is computed (nm).

RefractiveIndexProviderCyl.set_changed()

Inform all connected receivers that the provided value has changed.

The receivers will have its changed attribute set to True and solvers will call the provider again if they need its value (otherwise they might take it from the cache.
