PPLN ridge waveguide

PPLNs are widely used in non-linear optics, in particular for manufacturing frequency conversion components.

We have developed a component based on our technologies for high efficiency frequency conversion applications (SHG, SFG, DFG).
We propose the modeling of the structure according to your specifications in order to establish the operating points as well as the custom manufacturing of the structure.

 

Specifications :

Type of conversion SHG / SFG / DFG / SPDC
Wavelength 750 nm – 3500 nm
Power limitation ~ 1 W CW
Efficiency (SHG) > 100%W-1cm-2
Length 5 mm -40 mm
Anti-Reflective coating On demand
Packaging / Pigtailing On demand
