Fabrication of efficient micro- axicon by direct electron beam lithography for long non- diffracting distance of bessel beams
In this thesis, a novel technique has been employed in the realization of micro-axicon by single-step processing via electron beam lithography (EBL). The proposed technique is a simple, reliable and reproducible method for the production of high quality Bessel beams with long propagation invariant d...

| Summary: | In this thesis, a novel technique has been employed in the realization of micro-axicon by single-step processing via electron beam lithography (EBL). The proposed technique is a simple, reliable and reproducible method for the production of high quality Bessel beams with long propagation invariant distances, in our configuration, in excess of 20 cm. |
