NOTE: The dither command is classed as an experimental feature in Finesse v2 A quick example for generating an error signal by dithering the mirror. For this we need to use the `dither` command. dither component_name f m order phase Where f and m are the dither frequency and modulation index. The first simple example […]

The quantum noise that limits the sensitivity of a detector can have multiple sources. The main contributor is usually the vacuum noise that enters into the interferometer from the dark or also known as the AS (Anti-Symmetric) port. More generally, vacuum noise will leak into the detector wherever there is an optical loss – which […]
When doing optical modal modelling you will at some point have to consider how some incident mode gets scattered by some deformation or effect into another mode. There is a lot of math to take in before you start calculating stuff but there is a good review of it all here: https://link.springer.com/article/10.1007/s41114-016-0002-8#Sec118 The computational problem […]
