ModePropagationConstantProvider
(data)¶Provider of the propagation constant [1/µm].
This class is used for propagation constant provider in binary solvers. You can also create a custom provider for your Python solver.
Parameters: | data – provided value or callable returning it on request.
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.
outModePropagationConstant
(n=0)¶Parameters: | n (int) – Value number. |
---|---|
Returns: | Value of the propagation constant [1/µm]. |
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.inModePropagationConstant = solver.outModePropagationConstant
Obtain the provided value:
>>> solver.outModePropagationConstant(0)
1000
Test the number of provided values:
>>> len(solver.outModePropagationConstant)
3

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.
