Polarization behavior of femtosecond laser written optical waveguides in Ti:Sapphire.
Ultrashort pulsed laser photoinscription of Ti:Sapphire crystals may result in the self-organization of nanoscale material redistribution regions in regular patterns within the laser trace and stress-induced birefringence around the laser trace. We report on the formation of anisotropic optical waveguides in Ti:Sapphire by a procedure that involves femtosecond laser inscription of adjacent nong...
متن کاملPhotorefractive effect and optical damage thresholds in z-cut swift heavy ion irradiation LiNbO3 waveguides
We have investigated the photorefractive effect and the corresponding optical damage thresholds of novel LiNbO3 waveguides fabricated by swift-ion irradiation. TEand TM-mode operation has been characterized and the influence of the beam propagation length analysed. The results are briefly discussed and compared with some data from other type of LiNbO3 waveguides.
متن کاملFemtosecond laser fabrication of integrated optical waveguides and microfluidic channels for lab-on-chip devices
We use a femtosecond laser to fabricate on a glass substrate both microfluidic channels and high quality optical waveguides, intersecting each other. Waveguide-channel integration opens new prospects for in-situ sensing in lab-on-chip devices. Introduction A lab-on-chip (LOC) is a device that squeezes onto a single glass substrate the functionalities of a biological laboratory, by incorporating...
متن کاملFemtosecond laser written embedded diffractive optical elements and their applications
Femtosecond laser direct writing (FLDW) has been widely employed to create volumetric structures in transparent materials that are applicable as various photonic devices such as active and passive waveguides, couplers, gratings, and diffractive optical elements (DOEs). The advantages of fabrication of volumetric DOEs using FLDW include not only the ability to produce embedded 3D structures but ...
متن کاملFabrication of fully integrated antiresonant reflecting optical waveguides using the femtosecond laser direct-write technique.
Utilizing a recently developed two-step fabrication process, we have experimentally demonstrated what is to the best of our knowledge the first ever integrated antiresonant reflecting optical waveguide (ARROW), directly inscribed into bulk optical glass. The waveguide consists of an array of high-index contrast rods that surround an unmodified core. The transmission spectrum reveals the formati...
