PPLN (ridge) waveguide  

 

The waveguide can be manufactured on a periodically poled crystal to form a frequency conversion waveguide. HCP provides two types of the waveguide to customers to satisfy the requirement of the different applications.

For the more technical introduction please see here.

 

Compared to the traditional ion or proton in-diffused waveguide, the ridge waveguide has a high damage threshold and wide-operation wavelength range due to the high refractive index difference of the core (LiNbO3) and the cladding. The good confinement leads to good conversion efficiency and feasibility of extremely low propagation losses.

 

Most of the waveguides are manufactured upon request, but some of them are available in stock for popular applications. See the typical specification below and just inquiry us with your specific wavelength.

 

Following table shows the typical specifications of the standard waveguide, for ordering:

  1.  Select the serial # covering your interested wavelength (e.g. 1064 nm SHG corresponding to WG-G)
  2.  Send an inquiry with specified wavelength to us and we will respond you the available waveguide length in stock.
  3.  For the wavelength not listed, please just send us the inquiry for detailed specifications.
