Large silicon carbide optics for manufacturability - NASA/ADS

For space-based use, projected needs are for large optics of the one-meter class that lie under 30 kg/m 2 in mass areal density. Current space programs using glass optics, such as Kepler, exhibit a mass of 45 kg/m 2 , while JWST beryllium optics, including hardware attachment, are as low as 18 kg/m 2 . Silicon carbide optics can be made lighter than glass, although not as light as beryllium

Selection of Silicon Carbide for Electro-optic

6H Silicon Carbide (SiC) is unsuited due to unfavorable properties in its absorption. After comparing the electro-optic response functions of similar materials and their overall electro-optic performances at optimal optical wavelengths, 3C SiC proves best suited for the measurement process. I. Introduction Previously implemented techniques for

High-Q suspended optical resonators in 3C silicon carbide

We fabrie suspended single-mode optical waveguides and ring resonators in 3C silicon carbide (SiC) that operate at telecommuniion wavelength, and leverage post-fabriion thermal annealing to minimize optical propagation losses. Annealed optical resonators yield quality factors of over 41,000, which corresponds to a propagation loss of 7 dB/cm, and is a significant improvement

SiC Optics - Aperture Optical Sciences - Optical Components

This silicon reacts with the carbon to form silicon carbide. The final product is a mixture of silicon, carbon, and reaction formed silicon carbide between the original silicon carbide particles. Reaction bonded silicon carbide has a low porosity (full density can be achieved but will contain a higher amount of residual silicon).

Silicon carbide - Wikipedia

Silicon carbide, also known as carborundum /kɑːrbəˈrʌndəm/, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions requiring high endurance, …
