The rapid surge of data transmission within computation, storage and communication infrastructures is pushing the speed boundary of traditional copper-based electrical links. Recent realizations of 100Gb/s wired links require advanced FinFET technologies, highcost packaging/cables and power-consuming equalization. High-frequency waves over dielectric waveguides have been considered as an alternative solution that exploits the low-loss, broadband medium while maintaining compatibility with existing silicon IC platforms. However, since its debut in 2011 [1], this scheme, previously using ≤140GHz carriers, has only achieved data rates of up to 36Gb/s [2]. It is expected that higher carrier frequencies (e.g. >200GHz) and multi-channel aggregation would further increase the data rate while shrinking the interconnect size; but that scheme has been hindered by challenges related to the required high-order multiplexer and ultra-broadband waveguide coupler operating efficiently at sub terahertz (sub-THz) frequencies. In this paper, using a 130nm SiGe BiCMOS technology, we present a multi-channel, multiplexer/coupler-integrated transmitter (Tx) that delivers a data rate of 105Gb/s (3×35Gb/s). To demodulate each channel, a 35Gb/s coupler-integrated receiver (Rx) is also developed. Our link, including the chipset and a 0.4mm-wide, 30cm-long dielectric ribbon, experimentally demonstrates the potential speed, efficiency, size and cost advantages of THz fiber links in high-speed inter-server and backplane fabrics. |
