Silicon Carbide Wafer Lapping - Polishing | SiC Wafer

Silicon carbide (SiC) is a rare naturally occurring mineral known as moissanite. This substance has been synthetically produced for industrial use since the late 19 th century. It was first used as an abrasive applicant, an early LED, a gemstone stimulant, and a protective coating.

Lightweighted telescope mirrors: Outstanding properties of

I- Silicon Carbide properties Silicon Carbide (SiC) is a compound of Silicon and Carbon. Its natural formation is due to electro-chemical reaction between sand and carbon at very high temperature. Nowadays, SiC is industrially manufactured for many appliions included the production of ceramics with outstanding mechanical properties.

Optical Kerr nonlinearity in a high-Q silicon carbide

We demonstrate a high-Q amorphous silicon carbide (a-SiC) microresonator with optical Q as high as 1.3 × 105. The high optical quality allows us to characterize the third-order nonlinear susceptibility of a-SiC. The Kerr nonlinearity is measured to be n2 = (5.9 ± 0.7) × 10−15 cm2/W in the telecom band around 1550 nm. The strong Kerr nonlinearity and high optical quality render a-SiC
