Balanced Homodyne Detection

Requirements

  1. Displacement noise of OMC/LMC mirrors
  2. Scatter loss in mirrors
  3. Cavity design: triangle, quad ring, quad zig-zag (reference the new OMC paper from Koj)
  4. Laser amplitude / frequency noise including DC offsets in various other lock points and motions to simulate bilinear noise
  5. Oscillator noise: AM / FM
  6. Aux length noise: MICH/PRC/ SRC
  7. Req. on offsets/asymmetries: arm finesse, arm reflectivity, mass imbalance of ETMs

Modelling/Noise Budget

  • Some BHD modeling is done in the OptimalGWextraction repo here.
