英文要約Title:Advanced Research Program for Energy and Environmental Technologies / Research and development of low power consumption, ultra-large port count and high-speed optical switching system for data center (FY2015-FY2016) FY2015 Annual Report

Research in the following technical areas is being conducted to demonstrate the feasibility of a new optoelectronic hybrid switching system with low power consumption, ultra-large port count and high-speed switching for data center applications. The major accomplishments in FY2015 are as follows.
(1)A-1:Research of optoelectronic hybrid switching system
Various switch architectures for a new optoelectronic hybrid switching system with low power consumption, ultra-large port count and high-speed switching are investigated.
(2)A-2:Research of specification of optical switch
Based on the research of switch architectures above, functions and target specifications to realize switching operation have been investigated to each part of the system.
(3)B-1:Research of control algorithm
We have discussed two types of the algorithm: service-oriented method and data-oriented method, as the candidates for efficient flow control algorithm for the optoelectronic hybrid switching system.
(4)B-2:Research of switch hardware control interface
The configuration of network controller to operate the optoelectronic hybrid switching system has been investigated.
(5)C-1:Research of high speed wavelength switching technology
The drive condition of a conventional wavelength tunable laser is examined for realizing wavelength switching time of a few 10 μs under the guaranteed condition of reliability.
(6)C-2:Research of wavelength-addressing type optical transceivers
Several controlling techniques for the synchronization between optical burst-mode on/off switching and high speed wavelength switching have been investigated. In addition, various requirements for the wavelength-addressing type optical transceivers have been investigated in order to narrow down the modulation and demodulation methods which enable transmission up to 1 Tb/s.
(7)D:Research of spatial type optical switching modules
We explore the possibility of delivery and coupling switch with high port counts (16 - 32) and short switching time (several tens of μs). Studies on switching materials such as silicon and their structures were started.
(8)E:Research of high-density shuffle wiring
We started the investigation of high-density wiring technique with weave configuration based on the currently proposed architecture.
(9)F:Research and Development Promotion Committee
The first meeting of Research and Development Promotion Committee which consists of external experts from academia and industry and researchers of each research organization was held on March 8th with participation of NEDO and METI.
