Abstract :
We have experimentally and theoretically demonstrated a suitable design for optical antennas with nanorods on a Si substrate to realize plasmonic integrated circuits (PICs). We show that the reflectance measurement results for gold nanorods arranged on the Si substrate correspond to the results calculated by the finite-difference time-domain (FDTD) method. Based on these studies, we designed a structure for the arrangement of aluminum nanorods for Si-PICs for a wavelength range of 800-2000 nm, to match the wavelengths of 1300 nm and 1550 nm that are commonly used in optical communication systems.
