py-optics

Python code to aid with calculations for nanophotonics. Currently it contains:

• lumicks.pyoptics.psf: code that calculates the point spread function (electromagnetic field distribution) of a focused laser beam with arbitrary wavefront. The code takes polarization into account
• lumicks.pyoptics.trapping: code that calculates the electromagnetic field distribution of a spherical particle at an arbitrary distance relative to a focused laser

All code is developed in-house at LUMICKS.

Py-optics is free to use under the conditions of the Apache-2.0 open source license.

How to get started

1. Create and activate a virtual environment. With conda:

   $ conda create -n py-optics python=3.12
   $ conda activate py-optics
   

   Py-optics is tested on Python version 3.9 to 3.12. On Windows, there is a potential performance improvement if numpy and scipy are installed with conda, as they are optimized to use the Intel MKL libraries.

2. Clone the repository:

   $ git clone https://github.com/lumicks/py-optics
   $ cd py-optics
   

3. Install the pyoptics package:

   $ pip install -e .
   

   Or, if you want to install the additional dependencies for the example Notebooks:

   $ pip install -e .[examples]
   

   To run the benchmarks, you'll need to install extra packages for testing:

   $ pip install -e .[testing]
   

Example Jupyter Notebooks are available in the examples directory:

4. Run the Notebook:

   $ cd examples
   $ jupyter notebook
