Optical Transformers with Integrated Couplers (OTIC) for Ultrahigh SERS Enhancement

Abstract

We have developed a fundamental understanding of the electromagnetic enhancement in surface-enhanced Raman spectroscopy (SERS) that enable us to design and fabricate nano-antenna arrays on silicon wafers using nanofabrication technologies compatible with current silicon CMOS foundries. We have developed three generations of optical antennas with increasing enhancement factors. The final nano-arch antennas exhibit a strong enhancement of 1.7x10^10. These antennas can potentially be fabricated on 12-inch wafers using standard optical lithography in CMOS foundries.
