Journal ArticleDOI
Optical RAM and integrated optical memories: a survey
TL;DR: State-of-the-art integrated optical memory technologies and optical RAM cell demonstrations describing the physical mechanisms of several key devices along with their performance metrics in terms of their energy, speed and footprint are reviewed.
Journal ArticleDOI
Optics in Computing: From Photonic Network-on-Chip to Chip-to-Chip Interconnects and Disintegrated Architectures
Theoni Alexoudi,N. Terzenidis,Stelios Pitris,Miltiadis Moralis-Pegios,Pavlos Maniotis,Christos Vagionas,Charoula Mitsolidou,George Mourgias-Alexandris,George T. Kanellos,Amalia Miliou,Konstantinos Vyrsokinos,Nikos Pleros +11 more
TL;DR: It is demonstrated how optically-enabled eight-socket boards can be combined via a 256 × 256 Hipoλaos Optical Packet Switch into a powerful 256-node disaggregated system with less than 335 ns latency, forming a highly promising solution for the latency-critical rack-scale memory disaggregation era.
Journal ArticleDOI

Theoni Alexoudi,D. Fitsios,Alexandre Bazin,Paul Monnier,Rama Raj,Amalia Miliou,George T. Kanellos,Nikos Pleros,Fabrice Raineri +8 more
TL;DR: In this article, a III-V photonic crystal (PhC) nanocavity, heterogeneously integrated on a silicon-on-insulator platform, is shown to be capable of exhibiting two elementary static random access memory (SRAM) cell functions individually, namely switching and latching operations under a high-speed, bitlevel regime.
Journal ArticleDOI
Dual SOA-MZI Wavelength Converters Based on III-V Hybrid Integration on a $\mu{\rm m}$ -Scale Si Platform
D. Fitsios,Theoni Alexoudi,George T. Kanellos,Konstantinos Vyrsokinos,Nikos Pleros,Tolga Tekin,Matteo Cherchi,Sami Ylinen,Mikko Harjanne,Markku Kapulainen,Timo Aalto +10 more
TL;DR: In this article, a dual-element optical amplifier-Mach-Zehnder interferometer (SOA-MZI) array hybridly integrated on a 4-μm silicon-on-insulator (SOI) waveguide platform through thermocompression bonding is reported.
Journal ArticleDOI
10 Gb/s optical random access memory (RAM) cell
TL;DR: This Letter demonstrates the first all-optical RAM cell that performs both Write and Read functionalities at 10 Gb/s, reporting on a 100% speed increase compared to state-of-the-art optical RAM demonstrations.
