Abstract
In this paper, a new method is proposed to provide an inter- and intra-chip optical interconnect at the standard telecommunication wavelength of 1550 nm. The proposed optical interconnect consists of two optical leaky- wave nano-antennas as transmitter and receiver. The leaky-wave antennas are fed through a hybrid plasmonic waveguide with low propagation loss. Since the propagation length of plasmonic waveguides is not so long, each plasmonic waveguide is coupled to a silicon waveguide through an optical coupler. In comparison with previously proposed method of optical interconnect, the most important advantage of our method is its planar structure which makes it fully integrable with the photonic integrated circuits (PIC). The Fluguet theorem and the theory of surface plasmons are used to obtain an analytical model for design purposes, and the accuracy of the proposed method is verified by a 3-dimensional full-wave numerical analysis.
