Fiber Pigtailed Free Space Interferometer

Reference: GPC-MZI-001

The MZI-001 is a fiber pigtailed compact Mach-Zehnder interferometer, based on freespace optics, for detecting changes in optical frequency. The device comes with two fast photodetectors for the balanced detection of the two complementary outputs of the interferometer.

Product description

Fiber Pigtailed Free Space Interferometer

The free spectral range (FSR) or zero-cross spacing of the device is accurately defined to within 2%, a clear advantage over the all-fiber approach. In addition, the FSR can be selected from 10 GHz to as high as 100 GHz when ordering, making it flexible for system integration. Finally, the MZI-001’s free-space optical design eliminates the polarization sensitivity commonly associated with all-fiber interferometers.
