General Information

The Thorlabs INT-MZI-xxx series MZI Clock Box is a subassembly to be used in swept
source OCT systems and other applications. It contains a fusion coupler network to
provide a Power Monitor signal as well as a k-Clock signal to monitor output power and
wavelength of a swept laser source. The used fusion couplers are optimized for flat
wavelength response and very low PDCR (polarization dependent coupling ratio change)
to make the Power Monitor signal nearly independent of input polarization changes.
The "Getting Started Quickly" section below gives an overview of how to set up the INT-
MZI-xxx series MZI Clock Box. Subsequent sections contain detailed information about
principle of operation, operating suggestions and technical specifications.
