KTP, LN, & Mg:LN Waveguides
Periodically Poled Nonlinear Waveguides
Potassium titanyl phosphate (KTP) is a nonlinear optical material that can be used for a variety of frequency conversion applications (both Type I and II), Bragg stabilization, and phase modulation. 

Lithium niobate (LN) waveguides allows for much higher conversion efficency for lower power applications

Magnesium doped lithium niobate (Mg:LN) is suitable for a variety of applications requiring coversion to visible and near-UV wavelengths

AdvR has the ability to custom manufacture waveguides for your application, including the ability to create multi-element waveguides with multiple interactions per waveguide. AdvR also offers fiber packaged options for our waveguides.
AdvR can address many research needs:

- Type I and Type II interactions
- High power handling
- Increased conversion efficiency
  using embedded waveguides
- Frequency Conversion within
  range of 350-4500 nm
- Second Harmonic Generation
- Sum Frequency Generation or Upconversion
- Difference Frequency Generation
- Downconversion
SHG from a KTP waveguide.
