Bragg Cladding Waveguides Demonstrated

Facebook X LinkedIn Email
In the Oct. 4 issue of Optics Express and in the Oct. 11 issue of Applied Physics Letters, scientists at Massachusetts Institute of Technology in Cambridge describe silicon-based, on-chip Bragg cladding waveguides that are compatible with CMOS fabrication processes. Potential applications include integrated photonics for telecommunications and biosensing. The waveguides comprise a low-refractive-index oxide core and layers of paired higher-index dielectrics. To demonstrate the structures, the researchers employed SiO2, Si and Si3N4, grown by the low-temperature oxide method and...Read full article
