A thin layer of a SU-8 submicrometer pattern produced by holographic lithography was directly used as the dry-etching mask in a chemically assisted ion-beam-etching system. With optimized etching parameters, etching selectivity of 7:1 was achieved to... Read More about Form-birefringence structure fabrication in GaAs by use of SU-8 as a dry-etching mask.

Implementation of a graded-index medium by use of subwavelength structures with graded fill factor (2005)
Journal Article

We present a novel configuration for the implementation of subwavelength-based graded-index devices. The proposed concept is based on the etching of one-dimensional subwavelength gratings into a high-index slab waveguide to achieve the desired effect...

Characterization of chemically assisted ion beam etching and Form birefringence structure fabrication in GaAs using SU-8 (2005)
Presentation / Conference Contribution

We describe an approach to use the thin layer of SU-8 submicron pattern produced by holographic lithography as dry etching mask in chemically assisted ion beam etching (CAIBE) system. The effect of chlorine gas flow on etched sidewall was investigate...

Ultra short surface plasmon polaritons in photonic crystal structures (2005)
Presentation / Conference Contribution

We present experimental characterization of femtosecond-scale surface plasmon polariton pulses, propagating along the surface of thin metallic film, perforated with a 2D array of circular nanoholes.

Characterization of surface plasmon polariton pulse propagation on thin metallic films and two dimensional nanohole arrays (2005)
Presentation / Conference Contribution

A variety of techniques, including spectral measurements, near-field, and time-resolved spatial heterodyne imaging technique are employed to investigate the properties of surface plasmon polaritons. Such techniques may prove useful for investigating... Read More about Characterization of surface plasmon polariton pulse propagation on thin metallic films and two dimensional nanohole arrays.
