Abstract
An on-chip wireless optical broadcast network for future multicore CPU
interconnections is introduced in this paper. A baseline topology is
composed of 32 identical transmitting/receiving optical dielectric rod
antennas arranged around a circular ring. To ensure balanced power
distribution between the channels, the optical antenna design was governed
by the antennas' far-field radiation pattern and near-field coupling. Over
the frequency range of 172 THz (1750 nm) and 222 THz (1350 nm), the
broadcasting network has average and minimum transmissions of -16 and -21.5 dB, respectively. The overall transmission efficiency is
maintained above 70% throughout the operating bandwidth. Results are
confirmed by the full-wave simulations based on finite integration and
finite element methods. For additional validation, an eight-channel
microwave broadcasting network is fabricated, and excellent agreement
between the full-wave design and measurements are obtained.
