PPLN, PPLT WGM (Whisper Gallery Mode)/PC (Photonics Crystals)/ Other special engineerable QPM structures do not only allow phase matching at conventional co-linear propagation or cavity configuration, but also allow flexible design of several novel structures. HCP's exellent lithogrophy and electric poling techniques enable your special applications.

   *The polish quality depends on the chip dimension, for more information you can refer the polish specifications.
