NTT Current-injection Photonic-crystal Laser will Reduce MPU Power Consumption by 40%
Tokyo, Feb 14, 2012 (JCN) - Nippon Telegraph and Telephone Corp. (NTT) has developed a current-injection photonic-crystal laser with ultralow power consumption that can be applied to off-chip and on-chip optical data transmission for microprocessors (MPUs), reducing MPU power consumption by approximately 40%.
This reduced power consumption in the ICT equipment will result in reduced heat generation, and can also be expected to reduce the power required for cooling, which currently amounts to about 30% of the power consumed by a data center.
This result will be announced in detail in the February 13 issue of Optics Express, which is published by the Optical Society of America.
Part of this research is supported by the "Research and development of photonic-network chip for the CMOS processor" project of the New Energy and Industrial Technology Development Organization (NEDO).
