Synchronization Module

BOC – Balanced Optical Cross Correlator

Lowest-noise synchronization of two femtosecond lasers

  • More than 5 mV/fs sensitivity
  • Lower than 0.5 fs noise floor
  • Less than 15 fs RMS timing jitter and timing drift

Description

The fully automated BOC precisely detects the relative time jitter between two independent optical pulse trains with identical center wavelengths.

BOC is used for sub-femtosecond fiber link stabilization over kilometer distances. Due to a balanced optical detection scheme, the BOC provides exceptionally high timing sensitivity, attosecond timing resolution, amplitude invariance and robustness against environmental fluctuations. The output of the BOC is a baseband voltage signal that is proportional to the relative time delay between the two sources. This output can in turn be used in a phase-locked loop to synchronize the two optical sources. Standard wavelengths are 800 nm, 1030 nm and/or 1550 nm.
