Hello Rafie,
Optiwave currently don’t offer tilted FBG component. However, we’ve developed the code for designing TFBG. We expect to have it integrated to OptiSystem and OptiGrating in the 3rd quarter of this year. on the other hand we are open to collaborate with researcher on their work and help investigating their designs. If you are interested, please contact me at ahmad.atieh@optiwave.com
