Abstract
We propose a new design for a passive photonic reservoir computer on a silicon
photonics chip which can be used in the context of optical communication applications, and study
it through detailed numerical simulations. The design consists of a photonic crystal cavity with
a quarter-stadium shape, which is known to foster interesting mixing dynamics. These mixing
properties turn out to be very useful for memory-dependent optical signal processing tasks, such
as header recognition. The proposed, ultra-compact photonic crystal cavity exhibits a memory of
up to 6 bits, while simultaneously accepting bitrates in a wide region of operation. Moreover,
because of the inherent low losses in a high-Q photonic crystal cavity, the proposed design is
very power efficient.
