Mach-Zehnder Interferometer K-Clock Box
The KCLK Series k-Clock Box is a timing device for swept-source Optical Coherence Tomography, designed to linearize the sampling of interferometric signals in k-space (𝑘=2𝜋/𝜆) rather than time or wavelength. It uses a Mach-Zehnder interferometer (MZI) with a fixed optical path difference (OPD) to generate zero crossings at uniform k-intervals, which are converted into digital pulses that trigger the analog-to-digital converter (ADC) for precise, k-linear data acquisition. The unit includes a fiber coupler network that provides both the k-clock and a power monitor signal to track laser output power and wavelength, with low polarization sensitivity. The spacing between k-clock pulses is determined by the MZI’s OPD, with larger OPD yielding higher clock frequencies and denser sampling.

System integration
Integration and compatibility
Use these checks to connect Mach-Zehnder Interferometer K-Clock Box to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM28, 780HP · Fiber Cover: 0.9mm Tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1225-1375nm, 780-925nm
- Check the OCT Component passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
