HC Photonics (HCP) provides high conversion efficiency PPLN waveguides (periodically poled lithium niobate waveguides) to enable full-spectrum applications (i.e. single photon or Solc filter modulator) available for up-conversion (SHG/SFG) and down-conversion (DFG/OPA/OPG) frequency mixing configurations.

Two types of the waveguide are available to fulfill different applications. One is a proton-exchanged waveguide (up to 50 mm long) and the other one is ridge waveguide for high power handling (i.e. >2 W at 780 nm output). Tailored waveguides are available based on specific demands.

Periodically poled lithium niobate (PPLN) crystal is a type of non-linear optical crystal with distinguished high conversion efficiencies and a wide transparent spectrum of 0.4-5μm. The 5% MgO doping in LiNbOÄ3 improves the damage threshold of the PPLN to a significant extent and broadens its phase-matching bandwidth. MgO: PPLN crystals exhibit a unique quasi-phase-matching (QPM) phenomenon, which allows the utilization of a higher nonlinear coefficient than in the case of birefringent phase matching.

Shalom EO offers standard and off-the-shelf MgO:PPLN crystal and waveguides for SHG of 976 nm to 2100 nm and for various upconversion and downconversion applications including DFG, SFG, OPO, and OPA. Different dimensions, MgO concentrations and AR coatings are available.

Octave Photonics provides supercontinuum generation waveguides that are packaged into easy-to-use devices. These devices feature standard fiber connectors and enable femtosecond lasers to be broadened to octave-spanning supercontinuum with low pulse energies (<150 pJ). The devices can be customized depending on the desired output spectrum.
