CMOS-compatible Zero-Index Metamaterial.” In . CLEO: Science and Innovations. Publisher's VersionAbstract. 2016. “
We present an on-chip Dirac-cone metamaterial with an impedance- matched zero refractive index at lambda = 1550nm. The design is a square array of air holes in 220-nm silicon- oninsulator (SOI) which offers compatibility with complementary metal-oxide-semiconductor (CMOS) technology.
