One of the promising organic nonlinear optical crystals, DAST is expected to be applied for electro-optic sampling and tera-herts radiation through differential frequency generation. DAST crystal was usually fabricated by solution method using a methanol as a solvent. Thin crystal was prepared to make its waveguide, though, we need to fabricate a serially grafted waveguide where DAST is only a small part of the waveguide and the rest of it will be a transparent polymer waveguide. We will discuss about the crystal growth and the waveguide fabrication of DAST through photo-bleaching.
