Abstract

The ever-increasing demand for bandwidth triggered by mobile and video Internet traffic requires advanced interconnect solutions satisfying functional and economic constraints. A new interconnect called E-TUBE is proposed as a cost-and-power-effective all-electrical-domain wideband waveguide solution for high-speed high-volume short-reach communication links. The E-TUBE achieves an unprecedented level of performance in terms of bandwidth-per-carrier frequency, power, and density without requiring a precision manufacturing process unlike conventional optical/waveguide solutions. The E-TUBE exhibits a frequency-independent loss-profile of 4 dB/m and has nearly 20-GHz bandwidth over the V band. A single-sideband signal transmission enabled by the inherent frequency response of the E-TUBE renders two-times data throughput without any physical overhead compared to conventional radio frequency communication technologies. This new interconnect scheme would be attractive to parties interested in high throughput links, including but not limited to, 100/400 Gbps chip-to-chip communications.

Summary

Introduction

A metal waveguide has been used to transfer microwaves with high energy efficiency. due to its high rigidity, a hollow metal pipe creating total reflection at the metal boundaries is expensive and inconvenient. As compared with the dielectric waveguide, the metal cladding of the E-TUBE prevents electromagnetic leakage and enables low bending loss, thanks to its high confinement. A single-sideband signal transmission enabled by the inherent frequency response of the E-TUBE achieves two-times data throughput without any physical overhead when compared with conventional radio frequency (RF) communication technologies.
