SUMMARY

The discussion focuses on modeling squeezed light and its evolution using optical modeling software such as OptiFDTD and ZEMAX. The user seeks to simulate an Optical Parametric Amplifier to generate squeezed states but encounters limitations in existing software capabilities. They mention RP Propulse as a potential tool for designing Optical Parametric Oscillators but are uncertain about its ability to model the evolution of squeezed light in 3D. The user is looking for alternative software options that can facilitate this modeling process.

TL;DR
Is there any way to model squeezed states of light in optical modelling software such as OptiFDTD or ZEMAX?
I would like to model squeezed light and its evolution (such as when passing through lenses after being generated) using optics software such as OptiFDTD or ZEMAX. However, I don’t see any way to make such states…my plan was to simulate an Optical Parametric Amplifier to generate these states but I can’t seem to find any way to do that. Is there any way to generate squeezed states of light in a 3D optical modelling software (that allows you to view properties such as phase after some evolution)?
 
Physics news on Phys.org
I found a software that models (or at least helps design) Optical Parametric Oscillators called RP propulse: https://www.rp-photonics.com/rp_propulse.html. However, I am unsure if this software models the evolution of squeezed light or properties such as phase in 3D.Moreover, I can't seem to get my hands on the software as I am doing this recreationally and am not working on this with any organization. Is there some similar program I could use for this? Any help would be appareciated.
 
Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
