Where to Buy Phase Modulators

Designed using state-of-the-art and proven lithium niobate technology, the MPZ-LN phase modulators are easy to operate and to integrate. Available at both 1550 nm and 1310 nm, with low insertion loss and high polarization extinction ratio, either AC and DC coupled for RAM and pyroelectrical effects control, these modulators offer the optimum for industrial Quantum Key Distribution (QKD) systems.

Exail near-infrared phase modulators NIR-MPX are a modulator family ranging from DC-coupled low-frequency modulators to wide bandwidths up to 30 GHz, requiring very low driving voltages and offering incomparable 300 mW optical powers handling capabilities. These products benefit from the technological mastery of the "Annealed Proton Exchange" (APE) waveguide manufacturing process. These modulators find a lot of interest in the laser application, such as Pound–Drever–Hall cavity locking as well as Spectral Beam Combining (SBC) and directed and high energy material processing lasers.

The optical spectral broadening ModBox-OSB can broaden an optical signal by modulating its phase with a very efficient LiNbO₃ phase modulator. A number of sidebands are created over a spectral width that can reach several hundred GHz. The ModBox-OSB contains a single tone RF generator, a white noise source or a PRBS source. It well integrates into laser chains such as High Energy Lasers (HEL) lasers or Spectral Beam Combining lasers architectures (SBC).

Using KTP, RTP and LiNbO₃ crystals, ALPHALAS offers phase modulators for various applications like active mode locking, side-frequency generation and laser resonator cavity control. In addition to the standard products designed for 1064 nm, other customer-specific wavelengths can be offered as well.
