Quantum Information Science
 


AdvR's KTP periodically poled waveguides have been used to produce promising results in the field of quantum information. Researchers can use Type I and Type II frequency conversion to make advancements. From SPDC, to ion-trapping, to entangled photon source, AdvR's patented poling technique allows you to determine the specific interaction.

Second harmonic frequency conversion examples
1550 nm <--> 775 nm
1310 nm <--> 655 nm
1064 nm <--> 532 nm
800 nm <--> 400 nm

Down conversion examples
- Degenerate type I
  532 nm --> 1064 nm
- Non-degenerate type I
  532 nm --> 800 nm + 1600 nm
  580 nm --> 930 nm + 1530 nm
- Degenerate type I
  658.5 nm --> 1317 nm
- Degenerate type II
  658.5 nm --> 1317 nm + 1317 nm
- Non-degenerate type II
  389 nm --> 776 nm + 780 nm

Dual-element waveguide allows you to develop correlated photon pairs
