초록 : 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. FLDW has been widely employed in various areas of photonic device fabrication such as active and passive waveguides, couplers, gratings, opto-fluidics and similar applications.
This talk will present the various use of FLDW towards the fabrication of custom designed photonic structures. First, diffractive optical elements (DOEs) and their integration with other photonic structures are demonstrated. These are important micro-optical elements that are building blocks in integrated optical devices including on-chip sensors and systems. Second, the most recent achievements in Townes Laser Institute involving various novel optical materials will be presented. The potentials of the novel optical materials including noble metal ion containing glasses that can be used for the next generation laser-written device platforms will be discussed as well.
