Fiber Fabry-Perot Interferometer

The FFP-I consists of a lensless, plane Fabry-Perot Interferometer with a single-mode optical fiber waveguide between two highly reflective multilayer mirrors. The FFP-I is manufactured directly with optical fibers, so no alignment or mode-matching is required.  The free spectral range (FSR) can be manufactured to customer specifications, and a TEC package is available for thermal stability and minor adjustments to the center bandpass frequency.

The picoWave® is Luna’s patented multi-wavelength reference that enables real-time wavelength calibration with picometer accuracy. Combining the uniform frequency spacing of the FFP-I, a wavelength marker of a Fiber Bragg Grating, and a built-in TEC for thermal stability, the picoWave® makes an ideal calibrated wavelength reference.
