Eulitha’s DTL technology is highly compatible for creating high-precision nanostructures on optical elements like lenses, mirrors, optical fibers, and gratings. This technology enhances the performance and functionality of these components, significantly advancing fields such as telecommunications, imaging, and photonics by ensuring detailed and accurate patterning. DTL uniquely is able to pattern high-resolution structures over curved substrates and substrates with large topography.
Eulitha’s DTL technology is pivotal in producing telecom gratings, critical optical components in fiber-optic telecommunication systems. This technology precisely manipulates light through diffraction, reflection, and filtering of specific wavelengths. It enhances network monitoring and sensing capabilities, enabling real-time network performance and health optimization.
Micro- and nanostructures with deep subwavelength periods, printed with DTL, significantly reduce reflections and enhance light transmission. Such anti-reflective surfaces are critical in applications ranging from eyeglasses and camera lenses to solar panels and electronic displays. By minimizing glare and reflections they improve visibility and image clarity for a wide range of optical devices.
Spectrometer gratings are used in many analytical and sensing applications, and DTL is a common way to produce them. Beyond extremely precise linear gratings, DTL also prints curved and chirped (variable line-space) gratings, combining optical functions such as imaging and focusing with wavelength dispersion.
Large-area diffraction gratings with extremely high pitch accuracy and wavefront control are a core DTL application. These gratings are essential for manipulating light emission in lasers, spectroscopy, and optical communications. The high precision and large-area printing capability of Eulitha’s tools enable gratings with an extremely high level of wavefront control, for example pulse compression gratings.
Wavelength Selective Switches (WSS) route individual wavelengths or wavelength groups in fiber-optic networks, above all in Dense Wavelength Division Multiplexing (DWDM) systems. They separate the incoming light into its wavelengths, switch each to the desired output port and recombine them, which lets operators reconfigure traffic dynamically. The high-precision diffraction gratings that do this separation and combination are manufactured with DTL.
Wire Grid Polarizers control the polarization of light with parallel metallic wires, usually aluminum or silver: fields oscillating perpendicular to the wires pass, parallel ones are reflected. This requires deep subwavelength periods, typically one third of the wavelength. Eulitha’s PHABLE technology produces large-area wire grid polarizers with the required periodicity and uniformity.
Diffractive Optical Elements (DOEs) rely on precise microstructures on optical surfaces, which DTL fabricates directly. These structures manipulate light by altering its phase, amplitude, and polarization, providing customized optical functions for advanced optical systems. The high-resolution patterning of DTL is what lets DOEs meet specific operational demands across technological fields.
Reticles are the crosshairs or aiming marks in riflescopes, binoculars and telescopes. Illuminated reticles use diffraction gratings to couple light into and out of a transparent glass substrate, much like the waveguides in AR displays. Eulitha’s DTL technology prints the periodic structures on such reticles.
