Holographic Fabrication of Periodic Microstructures by Interfered Femtosecond Laser Pulses

Chiral microstructures (spirals) fabrication by holographic lithography.

We present an optical interference model to create chiral microstructures (spirals) and its realization in photoresist using holographic lithography. The model is based on the interference of six equally-spaced circumpolar linear polarized side beams and a circular polarized central beam. The pitch and separation of the spirals can be varied by changing the angle between the side beams and the ...

Fabrication of three-dimensional periodic microstructures in photoresist SU-8 by phase- controlled holographic lithography

Three-dimensional (3D) periodic dielectric structures were recorded in a commercial photoresist SU-8 by exposure to intensity patterns created by five interfering coherent femtosecond Ti : sapphire laser pulses. Periodic symmetry of these patterns was controlled by the choice of mutual convergence angles of the beams as well as their phases. The fabricated structures are mechanically and chemic...

Analysis of the holographic reciprocity law for dichromated gelatin.

The holographic reciprocity law for dichromated gelatin is investigated experimentally. The results obtained show that this law does not hold true for this material.

Design and Fabrication of Photonic Microstructures by Holographic Lithography and Pattern Transformation

The creation of periodic structures in nanoor micro-scale is an exciting challenge of materials science. Meanwhile, the structures with alternating periodic dielectric constants, known as photonic crystals, are great potentials for many applications in optical integrated circuits. In this dissertation, we design and fabricate periodic two(2D) and three-dimensional (3D) photonic microstructures ...
