Overview
The MPC-3X is the three-channel version of the Luna (formerly General Photonics) PolaRITE III mini dynamic polarization controller. It is an electrically controlled, all-fiber polarization controller based on fiber squeezing technology, packaged in a low-profile enclosure 0.63 inch high for integration in test equipment, fiber sensors, fiber lasers and optical network modules.
With three fiber squeezers, the MPC-3X can generate any polarization state on the Poincaré sphere from an arbitrary input polarization state. Each fiber squeezer is driven by a 0-150 V analog control voltage. The four-squeezer MPC-4X variant adds an extra degree of freedom for reset-free operation and polarization scrambling.
The all-fiber construction keeps insertion loss and back reflection low, gives minimal activation loss and operates over a wide wavelength range. An athermal package design provides temperature stability over a wide temperature range.
The controller can be paired with a miniature piezo driver card, available integrated as the PCD-M02, so that the polarization can be set with either a digital or an analog control signal.
