MOXTEK has developed 8-inch nanoimprint processes to manufacture subwavelength 3-D nanostructures. We offer imprinting, etching, and fabrication capabilities for your product needs on glass-like wafers and have successfully tested silicon, display glass, and sapphire as substrate materials. We also demonstrated the capability to imprint a 4-state pixelated aluminum wire-grid polarizer with 7μm pixel pitch and 144nm wire pitch as shown in the images below. Thus far, Moxtek has imprinted feature sizes less than 30nm wide and less than 50nm tall.

MOXTEK’s broadband wire-grid polarizers provide excellent polarization contrast and transmission at wide cone angles. These inorganic polarizers are extremely small and are designed to tolerate high temperatures. (more…)

April 29, 2020 – MOXTEK announces the transfer of the ICE Cube™ wire-grid polarizing beamsplitter (PBS) product line to Meadowlark Optics.

Fluorescence and label free based detection methods serve as very effective means to identify and detect literally any biomolecule of interest. Though very useful, both methods offer relatively low signal to noise ratios (SNRs). By incorporating metallic nanostructures, which provide highly focused and enhanced optical fields, one can boost the SNR by several orders of magnitude, thereby resulting in a highly enhanced fluorescence response. Furthermore, nanofocusing of the light at the metallic surface allows for label free sensing of target biomolecules. Building on years of expertise, Moxtek has developed inexpensive and reliable methods to obtain uniform wafer scale metallic and dielectric nanostructures that can be used as Biochips for these applications. Additionally, our nanofabrication expertise at Moxtek allows us to also provide numerous photonic crystal based structures. See the PDF here.

Moxtek^® has been producing nanostructured optical components for over 20 years. We offer high volume wafer replication of various nanostructure devices. Our versatile capabilities are used to manufacture functional nanostructure devices including: metalens arrays, waveguides, patterned metasurfaces, Diffractive Optical Elements (DOEs), photonics crystals, and biosensor arrays. These devices are used for imaging, illumination, and display systems for a variety of applications including: automotive, medical/dental imaging, camera systems, and many others.

Moxtek offers state of the art NIL volume manufacturing on 8-inch wafers. We have demonstrated stamp life up to 1300 prints with SPC monitoring of CD repeatability down to 30nm.

ProFlux® Nanowire® Ultraviolet polarizers offer excellent solutions for UV and deep UV applications (240nm to 400nm). High transmission and high contrast choices are available. High transmission products are indicated by UVT and high contrast products by UVD. UVD products can be used in spectrophotometers where the small size, wide acceptance angle, grid uniformity, and broad band capability offer substantial performance enhancements.
