Abstract
This paper examines the properties of optical resonator memory cells, in which a
data bit is stored in a high-<i>Q</i> optical resonator. It is shown that
resonator-based optical memories are ultimately limited by losses in the resonators, by
the extinction ratio and chirp of the variable coupling medium that injects and extracts
data into and out of the resonators, and by chirp on the input signal. Using a simple
analytical model and accurate field-based simulations, we analyze the performance of a
ring-resonator optical memory cell and compare this with the performance of slow light
delay line buffer memories and complementary metal–oxide–semiconductor embedded dynamic
random-access memory.
