Abstract
Nowadays, a huge data traffic requires a high-speed processing, so the use of optical memories is a logical solution for high speed data processing. In this paper, a large-scale parallel integration of wavelength addressable optical bit memories is presented based on three photonic crystal nanocavities (C1, C2, and C3) filled with liquid crystal. Each cavity is storing two different wavelengths, where each wavelength is representing a single bit. We have calculated Q factors in basing and unbiasing states for C1, C2, and C3. Also, the group velocities across the storage cell have been measured in the biased and unbiased cases for all cavities to confirm the storage and confinement. The maximum consumed power for six bits optical memory is only 13 nW.
