Ultrafast Bit and Byte addressing of All-Optical Memory based on Microring Resonators for Next-Generation Optical Networks

Yingyan Huang, Seng‐Tiong Ho

We present a novel ultrafast all-optical memory scheme that has the potential to meet the demanding requirement for 100 Gb/s all-optical data storage. The all-optical memory integrates an all-optical ring resonator flip-flop with an innovative GMCI (gain manipulation of coupler interference) based all-optical switch for ultrafast READ and WRITE. The potential device performance advantages include very low operating power for the memory element (<50 muW per bit), low read-write power for the GMCI based all-optical switch (<0.5-5 mW), ultrafast operation (10-100 Gbit/s), very compact size (<10 mumtimes10 mum per bit), addressable at bit or byte level, and monolithically integrated on InP chip

Optically simulating a quantum associative memory

John C. Howell, John A. Yeazell, Dan A. Ventura

This paper discusses the realization of a quantum associative memory using linear integrated optics. An associative memory produces a full pattern of bits when presented with only a partial pattern. Quantum computers have the potential to store large numbers of patterns and hence have the ability to far surpass any classical neural-network realization of an associative memory. In this work two three-qubit associative memories will be discussed using linear integrated optics. In addition, corrupted, invented and degenerate memories are discussed.

Novel ultra low power optical memory using liquid crystal

Salah S. A. Obayya, Mahmoud A. Elrabiaey, Hossam M. H. Shalaby +1 more

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.
