Amorphous SiC/SiO2 distributed Bragg reflectors (DBR) deposited by ion beam sputtering at room temperature is reported on in this letter. The DBR consists of only 2.5 pairs and exhibits high peak reflectivity (84%) around similar to 1.7 mu m with a full width at half maximum of about 1000 nm. The measured reflectivity spectrum is well reproduced by the equivalent layer theory by using the measured refractive indices of SiC and SiO2 and including absorption losses.

Abstract
Amorphous SiC/SiO2 distributed Bragg reflectors (DBR) deposited by ion beam sputtering at room temperature is reported on in this letter. The DBR consists of only 2.5 pairs and exhibits high peak reflectivity (84%) around similar to 1.7 mu m with a full width at half maximum of about 1000 nm. The measured reflectivity spectrum is well reproduced by the equivalent layer theory by using the measured refractive indices of SiC and SiO2 and including absorption losses.
