Current roadmaps show that the semiconductor industry continues to drive the usable Rayleigh resolution towards thefundamental limit (for 50% duty cycle lines) at k 1 =0.25. This is being accomplished through use of various resolutionenhancement tech

It is shown that the efficiency of metal-semiconductor-metal (MSM) detectors can be improved using a dielectric diffraction grating, positioned appropriately above the detector. The grating has the effect that the light is channelled into the grooves

Diffractive optical elements for high-power lasers offer interesting applications in addition to conventional refractive and reflective optics like lenses and mirrors. Their function is based on diffraction at small surface structures in the scale of

A novel design for imitating continuous phase profiles by binary sub-wavelength structures is presented. The continuous phase profiles, in general blaze structures, are required to achieve high diffraction efficiencies. The working principle has rece

Waveguide structure in this context means metallic coated gratings which have periods smaller than the wavelength of the incident light. The grooves of these subwavelength gratings can be regarded as waveguides. Since the phase velocity depends on th

Refractive or diffractive microlenses have already been reported. Here we discuss two examples of microlenses where the generation process and the interferometric control are strongly interwoven. For refractive lenses we use lenses melted in photores

Using technologies originally developed for the electronics industry, like photolithography, e- beam writing, and dry etching, good quality diffractive elements with useful physical properties can be produced directly upon a given surface. Particular
