Simphony 0.8.0rc0

0.8.0rc0 - 2026-05-29

Release candidate for archiving the current time-domain simulator implementation.

Added

• Citation metadata for GitHub and Zenodo.
• Release workflow handling for release-candidate GitHub prereleases.

Fixed

Changed

• Prepared the time-domain simulator branch for Zenodo DOI archival.

Simphony 0.7.3

0.7.3 - 2025-10-27

Minor bug fixes.

Added

Fixed

• Bug with sax 15.0.0 and later where simphony fails to import get_ports.
• Bug in SiPANN integration in which parameters passed to angled_half_ring were overwritten and theta parameter was missing.
• Missing dependency for parsimonious.
• Several pytest issues.
• Syntax errors preventing make patch, make minor, and make major from running.
• Bug with group delay that was ignored in lumerical file parser. Lumerical output files calculated with "include group delay" in the s-parameter matrix sweep dialogue were imported with incorrect phases due to ignoring group delay.

Changed

Simphony 0.7.2

0.7.2 - 2024-01-09

Minor bug fixes.

Added

• Note added to documentation informing users that port names must be valid
  identifiers.

Fixed

• Bug in loss of waveguide in ideal library was fixed.

Changed

• Port names in sax are now required to be valid Python identifiers.
  In practice, this means that spaces previously present in port names are now
  replaced with underscores.

Simphony 0.7.1

0.7.1 - 2024-01-09

Minor bug fixes.

Fixed

• Bug in some of the tests after the models were rewritten.
• Bug in string formatting for parameterized filenames in SiEPIC libraries.

Simphony 0.7.0

0.7.0 - 2024-01-06

This is a refactor of simphony that uses SAX
as the s-parameter solver backend.

Added

• Quantum simulations tools for simphony. The main advantage here is the use of
  classical s-parameter models for quantum simulations.

Changed

• The s-parameter solver backend is now SAX.
• Simphony inherits the ability to run simulations on GPU's using
  JAX. This means that simphony code
  now uses jax.numpy in place of numpy.
• SiPANN wrappers are now built into simphony, instead of into SiPANN. In order
  to use them, you must still install SiPANN.

Removed

• The majority of the package has been reimplemented or reorganized or made to
  depend on other packages. This means that the majority of the code has been
  removed, and this version of simphony is not compatible with previous
  releases.

Simphony 0.6.1

[0.6.1] - 2022-02-18

This patch makes the CMRR take beam splitting into account.

Simphony 0.6.0

[0.6.0] - 2022-01-12

This version includes Relative Intensity Noise modeling and CMRR.

Added

• Laser RIN model
• Differential Detector CMRR

Changed

• coupling_loss now specified in dB

Simphony 0.5.1

[0.5.1] - 2021-11-09

This patch update makes filtering for simulation devices work again.

Simphony 0.5.0

[0.5.0] - 2021-10-20

This update adds a new way to run simulations. Sources and Detectors can be connected to circuits during a simulation context. When the context ends, the sources and detectors disconnect from the circuit so it can be used again.

Added

• Simulation Contexts
• Noise simulations

Simphony v0.4.0

[v0.4.0] - 2021-06-08

This update changes the way components are connected and pins are handled for the end user, and refactors the API substantially.

Added

• SiPANN Wrapper included in simphony now
• Fix to issue 17 in SiPANN, now devices work in simphony regardless of number of pins.

Changed

• refactored API
• simulator result units match initial units
• reorganize modules
• general code clean up
