Abstract:
lectronic circuits have evolved into multifunctional and highly integrated
systems. Moreover, the demands for high-speed data transfer are ever
increasing that often require multi-gigahertz clock frequencies and
ultra-high-speed and wideband data transmission between chips. However, fundamental interconnect limitations prevent from full accomplishment of
multi-gigabit per second data rates. Most importantly, increased conductor
and dielectric losses at high frequencies can significantly reduce the
channel bandwidth. In addition, crosstalk and electromagnetic interference
further deteriorate the system performance, especially in compact routing
networks. Therefore, alternative interconnects that enable
ultra-high-speed/high-frequency signaling while maintaining good signal
quality are needed. This work proposes a new method of high-speed data
transfer by utilizing waveguide-type interconnects, which offer efficient
and confined data transmission due to their low loss and excellent isolation
properties. Excellent transmission quality is demonstrated experimentally up
to a data rate of 5 Gb/s. Furthermore, to compensate for the relatively
larger footprint occupied by the waveguide compared to conventional printed
lines, a substrate reuse approach is proposed by inserting additional
lowpass channels inside the waveguide. This hybrid technique proves to
increase the aggregate transmission capacity (to 15 Gb/s) by simultaneously
utilizing the lowpass and bandpass channels. Finally, an alternative
parallel data transmission system is introduced by harnessing multimode
transmission through the same waveguide channel and using orthogonal modes.
A number of transition structures and mode launchers to excite and retrieve
TE10 and TE20 modes are presented. Experimental characterizations demonstrate excellent transmission quality through the dual-channel system
for a data rate of 1 Gb/s/channel.
