In this work we demonstrate, for the first time to our knowledge, a novel subwavelength optical element for the selective excitation of the TE/sub 01/ mode inside a 300-/spl mu/m bore diameter hollow-glass waveguide (HGW) in order to reduce the trans

Bending loss is the biggest drawback to hollow waveguides used for light delivery applications such as laser ablation. One way to overcome this limitation without changing the fiber design or fabrication is to engineer the input light to excite speci

In this paper we present the fabrication of refractive micro optical elements by additive sculpting of the photoresist using binary amplitude masking techniques. We also present the fabrication of micro optical elements by pre sculpting the photoresi

In this paper, we present a new photo-mask technology capable of forming a continuous relief micro-optic profile on thick photo-resist. This technique eliminates many of the drawbacks of gray-scale and half-tone masking technology. An optical stepper

The use of a vortex phase optic as a coupling element for a dual mode step index fiber system is presented. We introduce a novel but rather simple coupling scheme for selectively exciting the LP11 mode in a step index fiber that is a single mode at a

In optical lithography the degradation of image quality due to aberrations present in the exposure tool is a serious problem. Therefore it is desirable to establish a reliable aberration measurement procedure based on the analysis of printed images i

In this paper, we present a method for incorporating diffractive optics on a photomask for aberration characterization. This allows for a manipulation of the incident illumination to the amplitude mask for estimating the aberration coefficients.

Micro-Optics have begun to play a key role in micro-photonic systems and devices. This is largely due to the fact that semiconductor processing has enabled one to incorporate complex optical functions and integration features into the actual optical
