A new type of photonic crystal all-optical switching based on the dynamical shift of defect mode has been designed. This photonic crystal is triangular lattice with circular air holes in silicon, in which line defects and point defects are included. A photonic crystal structure introducing both point and line defects which has quality defect mode is designed. After that, point defects have been filled with the Kerr nonlinear optical material-polydiacetylene para-toluene sulfonate (PDA-PTS). With regulating the control light, the defect mode brings the dynamical shift, and accordingly it can be controled the signal light on and off. The two-dimensional finite-difference time-domain (FDTD) calculation has been used to numerical demonstration. The results show that the switch has great extinction ratio, low threshold power density, and fast switching time. The photonic crystal all-optical switching based on the dynamical shift of defect mode has an important academic significance to the high-speed all-optical communications, as well as the optical computing technology in the future.

The work focused on the promoting effect of humanized management on education. Humanized management attracts plenty of attention in the knowledge era. The scientific development of human potential has become an important subject of modern management. Reflections were primarily made on the humanized management. Subsequently, a discussion was presented about the importance and promoting effects of humanized management on education. On this base, concrete measures were proposed to enhance humanized management. © 2015 Taylor & Francis Group, London.

The desktop phone may seem like a dinosaur in this mobile-first era, but with a 7-inch touch screen and an integrated camera on its latest model, Alcatel-Lucent Enterprise begs to differ. The 8088 Smart Deskphone, launched Monday, has been developed to feel at home in a world where users are becoming accustomed to touch-centric products and relying more on smartphones for communicating. From the screen on the 8088, users can search for contacts, set alarms and access voice mail. There are APIs available for customization. The phone's features can at the same time be controlled from a smartphone, tablet or laptop. The user can also start a call on a deskphone and then transfer it to a smartphone or vice versa. The integrated 5-megapixel camera is meant to be used, among other things, for video conferencing. To build on that, the 8088 also has an HDMI output for screen replication on a bigger display for room-based video collaboration. The phone will start shipping in April. Pricing wasn't immediately available. Alcatel-Lucent Enterprise in its current form was born last year when Alcatel-Lucent sold the business to China Huaxin, as part of a reorganization to turn its fortunes around. The phone, along with an upgraded version of OpenTouch Suite, was launched at the Cebit trade show in Germany and at Enterprise Connect conference in Orlando, both taking place this week.

Alcatel-Lucent has revealed that it is in discussions with technology investment company China Huaxin to sell off its enterprise phone business. The French telecoms equipment maker included the news in its end-of-year financial results, where the company recorded encouraging results following losses last year. China Huaxin’s offer for the acquisition of 75 percent of Alcatel-Lucent Enterprise valued the business at €268 million (£222 million). Under the terms of the deal, Alcatel-Lucent would retain a 15 percent minority interest in the business, but all contracts and employees would transfer to the Chinese company. The two companies are already partners in a joint venture in the Chinese market, targeting the sale of communications products and services to corporations in the country. Alcatel said it expects to sign the deal by the second quarter of this year, and is aiming to close it by the third quarter pending regulatory approval. The sale is part of a longer-term strategy by Alcatel’s new chief executive Michel Combes, who took over in April 2013 and pledged to deliver €1 billion in asset sales by 2015 as part of his ‘Shift Plan 2015’. The sale follows the news in December that Alcatel would be selling its US satellite-communications subsidiary LGS Innovations to an investor group led by US-based Madison Dearborn Partners for a reported $200 million. In its end of year results, Alcatel revealed it had recorded fourth-quarter revenues of €3.93 billion euros (£3.26 billion). This was lower than analyst expectations; however the company also recorded an operating profit of €307 million (£255 million) and a gross margin of 34 percent, both of which were better than expected. However, the company suffered from a major writedown on its mobile business and restructuring costs from layoffs, after announcing last October that it planned to cut 10,000 jobs worldwide over the next two years in order to save money. It also consumed more cash than it generated for the second year in a row, recording negative free cash flow of €636 million (£527 million). This meant that the company still recorded a net loss for the year, although 2013’s loss of €1.3 billion (£1.07 billion) was significantly down from the €2 billion (£1.66 billion) loss in 2012. The reduction shows that the company had benefitted from major cost-cutting and a more focused products offerings, and is on track to fulfil the goals of its Shift Plan 2015, which focuses on continued cost reductions, cash generation, and profitable growth. At the recent CES event, Alcatel had signalled that its consumer device division would be a major part of its efforts for 2014, revealing a new 5.5 inch smartphone and two tablet devices (pictured above), which were heralded by a company spokesman as, “a great first step in our product alignment for smartphones and tablets”.

Hewlett-Packard Co. sold a majority stake in its Chinese server, storage and technology assets for $2.3 billion to Tsinghua University, becoming the first major U.S. technology company to pass control to local owners since the government stepped up restrictions on foreign firms. A group owned by the Chinese university, Tsinghua Holdings, will purchase the 51 percent stake in a new business called H3C. The deal values the businesses at $4.5 billion net of cash and debt, the companies said Thursday in a statement. China has been encouraging the use of local suppliers and aims to purge most foreign technology from the country’s banks, military and government enterprises by 2020, people with knowledge of the matter said in December. By selling control of the businesses to Chinese investors, Hewlett-Packard seeks to win sales to state-owned companies. The Palo Alto, California-based company will maintain full ownership of its China-based enterprise services, software, HP Helion Cloud, Aruba Networks, printing and personal-systems businesses. Hewlett-Packard’s networking units had “a rougher than anticipated” quarter, Chief Executive Officer Meg Whitman told analysts in late February, noting that they struggled in China especially. Networking sales in the three months ended January 31 fell 11 percent from a year earlier. Under the deal, H3C will become a subsidiary of Unisplendour, a publicly traded unit of Tsinghua Holdings. Unisplendour, a software vendors and system integrator, has been in a long-term strategic distribution partnership with Hewlett-Packard since 1999. The new H3C generated adjusted revenue of $3.1 billion and adjusted operating profit of $400 million last year, according to the companies’ statement. Hewlett-Packard shares rose 2.3 percent to close at $33.83, leaving the stock down 16 percent this year. Bloomberg News reported in March that Tsinghua, ICBC International Ltd.’s direct-investment arm RT Capital and state-owned China Huaxin Post & Telecommunication Economy Development Center were on a short list of bidders for the Hewlett-Packard units.
