| Abstract | Since the first demonstration of femtosecond laser written waveguides in 1996, femtosecond laser direct writing (FLDW) has been providing a versatile means to fabricate embedded 3-D microstructures in transparent materials. The key mechanisms are nonlinear absorption processes that occur when a laser beam is tightly focused into a material and the intensity of the focused beam reaches the range creating enough free electrons to induce structural modification. This dissertation was an attempt to make an improvement on the existing FLDW technique to achieve a reliable fabrication protocol for integrated optical devices involving micro diffractive optical elements and laser-structures exhibiting second order nonlinear optical properties. Relaxation processes of directly-written structures in chalcogenide glasses have been also investigated. |
