Prism-shaped hyperlens for subwavelength focusing of light
Applied Optics
|February 24, 2022
Abstract:
Subwavelength focusing of light is on-demand for overcoming the diffraction limit of light for applications such as photolithography. A prism-shaped hyperlens capable of focusing incident light to a subwavelength scale is proposed. The lens lifts the complexity of previous structures and achieves a spot size of about λ0/4 at the free-space wavelength λ0=365nm. Another feature of the proposed lens is that it consists of planar input and output ports, which have been a design challenge for focusing lenses in recent years.

3.3K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
