PPLN Mixers

Electro-optics

HC Photonics PPLN Mixers are compact, robust optical modules that integrate high‑quality periodically poled lithium niobate (MgO:PPLN) for efficient wavelength conversion using nonlinear processes such as second‑harmonic generation (SHG), sum‑frequency generation (SFG), difference‑frequency generation (DFG), and spontaneous parametric down‑conversion (SPDC).

PPLN mixers are offered in various formats (waveguide, bulk, cavity, and pulse mixers) with fiber‑coupled or free‑space interfaces, covering UV/visible to NIR/MIR wavelengths and delivering high efficiency, low noise, and reliable performance for applications from laser sources and spectroscopy to quantum frequency conversion and photon‑detection systems.

What are PPLN Mixers?

PPLN Mixers are compact wavelength-conversion modules that integrate Periodically Poled Lithium Niobate (PPLN) chips into a robust package to efficiently convert input laser light to new wavelengths using nonlinear optical processes such as second harmonic generation (SHG), sum-frequency generation (SFG), difference-frequency generation (DFG), and quantum frequency conversion

What nonlinear processes can PPLN Mixers perform?

They support multiple nonlinear frequency conversion processes, including: SHG (doubling frequency), SFG (sum of two frequencies), DFG (difference of two frequencies), SPDC for quantum photon generation.

How are the mixers interfaced?

PPLN Mixers can be made with either: Fiber-coupled interfaces (polarization-maintaining fiber), Free-space optics, Or hybrid combinations like 1×1, 2×1, 1×0, etc.

What wavelengths can PPLN Mixers generate?

They can produce outputs from UV/visible to near-infrared (NIR) and mid-infrared (MIR), depending on configuration and pump lasers.

Can the mixer be customized?

Yes - HC Photonics can customize mixers for specific input wavelengths, output targets, fiber types, and performance requirements on request.
