The MZI-001 is a fiber pigtailed Mach-Zehnder free space interferometer that detects changes in optical frequency. The device comes with two high speed photodetectors for the balanced detection of the two complementary outputs of the interferometer.
The free spectral range (FSR) or zero-cross spacing of the device is defined to within 1% with no polarization sensitivity. The FSR is user defined between 10 GHz and 100 GHz.
