Femtosecond laser processing of diamond and L-threonine organic crystal for photonic applications
Abstract
Processing of materials by ultrashort laser pulses allows high precision-patterning of 2D and 3D micro-nanostructures, and has become a cornerstone technology for a wide range of areas (1). Several ultrashort laser-based fabrication techniques, such as fs-laser micromachining, fs-laser induced forward transfer (fs-LIFT), and two-photon polymerization (2PP), have been used for the development of photonic and optoelectronic devices. Such approaches do not require masks, harsh processing conditions nor a cleanroom (2); besides, they enable the fabrication of 3D microstructures with arbitrary geometries and sub-diffraction features.5 Moreover, a large variety of materials can be employed, such as glasses, polymers, semiconductors, crystals, and so on. Hence, fs-laser microfabrication is an interesting single-step approach that can be used for fabricating a myriad of components, such as splitters, interferometers, resonators, and waveguides (3-5). To achieve the integration required for the next generation of photonic devices, it is necessary to combine resonant microstructures and waveguides in a single three-dimensional (3D) platform.
