Spatially resolved measurement of femtosecond laser induced refractive index changes in transparent materials.
We present a practical method to determine femtosecond laser induced refractive index changes in transparent materials. Based on an iterative Fourier transform algorithm, this technique spatially resolves the refractive index of complex structures by combining the dimensions of the modified region with the corresponding phase change extracted from far-field intensity measurements. This approach...
متن کاملLinear and Nonlinear Refractive Index Changes in Spherical Quantum Dot
In this study, refractive index changes associated with intersubband transitions in a spherical quantum dot, GaAs/AlxGa1−xAs, have been theoretically calculated in the presence of impurity. In this regard, the effect of dot radius, stoichiometric ratio, impurity and incident optical intensity on the refractive index changes have been investigated for the transitions between higher energy states...
متن کاملCharacterization of a Chemically Amplified Photoresist for Simulation using a Modified “Poor Man’s DRM” Methodology
As we enter the DUV lithography generation, the developmental phase of the photolithography process is becoming crucial due to the high costs associated with the lithography equipment. Improvements in the modeling of chemically amplified resists are necessary to extract the maximum possible information from the minimum amount of experimentation. The poor man’s dissolution rate monitor (drm) met...
متن کاملNumerical Approach to Modeling and Characterization of Refractive Index Changes for a Long-Period Fiber Grating Fabricated by Femtosecond Laser
A 3D finite element model constructed to predict the intensity-dependent refractive index profile induced by femtosecond laser radiation is presented. A fiber core irradiated by a pulsed laser is modeled as a cylinder subject to predefined boundary conditions using COMSOL5.2 Multiphysics commercial package. The numerically obtained refractive index change is used to numerically design and exper...
متن کاملFemtosecond laser micro-structuring and refractive index modification applied to laser and photonic devices
Rapid progress has been made in the last few years in the development direct-write, femtosecond laser micro-structuring and waveguide writing techniques in various materials, particularly semiconductor and other photo-sensitive glasses. There is considerable potential for this becoming a disruptive technology in photonic device fabrication, perhaps even leading to the development of devices tha...
