NTT develops current-injection photonic-crystal laser
- Towards ultralow power consumption microprocessors -

Nippon Telegraph and Telephone Corporation (NTT, CEO: Satoshi Miura, Tokyo) has developed an current-injection photonic-crystal laser*1 with ultralow power consumption that can be applied to off-chip and on-chip optical data transmission for microprocessors*2.

Microprocessors in servers, routers and other ICT equipment consume a large amount of power. This laser is expected to reduce microprocessor power consumption by approximately 40%.
In addition, the lower 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 a project of the New Energy and Industrial Technology Development Organization (NEDO), called “Research and development of photonic-network chip for the CMOS processor.”

日本最大電信運營商NTT Docomo已研發出世界第一支透明觸控手機，正反兩面都能使用，這支手機將在5月30日的東京WIRELESS JAPAN大會現身，之後可望運用在智慧型手機上。

NTT Docomo表示，隨著智慧型手機快速普及，這種雙面觸控螢幕可以為用戶提供全新的操作體驗。據日媒報導，透明雙面觸控採用了畫質鮮麗細膩的OLED螢幕，具有可正反面操作、透明和彩色等特點，無論在正面或是背面，都可以滾動、打開、關閉、滑動切換等。

另外，透過APP可以使操作方式更具變化，也由於正反都可觸控，大拇指和食指都被充份利用，操作舒適度高。但有一缺點是，如果在室外強光下，可能難以使用，需待進一步改善。

類似產品在2009年已有索尼愛立信的Xperia Pureness，不過是支單色手機。目前NTT Docomo未透露合作研發廠商和上市時間。
