PPKTP for SPDC
We offer PPKTP for both Type 0 and Type II SPDC processes.
In Type 0 SPDC process the pump and the generated photons (signal and idler) have the same polarization:
In Type II SPDC process, the generated photons have orthogonal polarizations:
We usually have in stock the most commonly used processes for operation close to room temperature:
Type 0: 405 → 810 nm + 810 nm
Type II: 405 → 810 nm + 810 nm
Type 0: 775 → 1550 + 1550 nm
Type II: 775 → 1550 + 1550 nm
Not your wavelengths? No problem! We also produce PPKTP crystals tailored to your specific process, with short lead-times. Just contact us!
