- 2015-04-24 Interaction between light and sound in nanoscale waveguide
- Scientists from Ghent University and imec announce today that they demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these scales – and pave the way for enhanced signal processing on mass-producible silicon photonic chips.
In the last decade, the field of silicon photonics has gained increasing attention as a key driver of lab-on-a-chip biosensors and of faster-than-electronics communication between computer chips. The technology builds on tiny structures known as silicon photonic wires, which are roughly a hundred times narrower than a typical human hair. - See Details

- 2015-04-24 New paper-like material could boost electric vehicle batteries
- Researchers at the University of California, Riverside's Bourns College of Engineering have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery.
This paper-like material is composed of sponge-like silicon nanofibers more than 100 times thinner than human hair. It could be used in batteries for electric vehicles and personal electronics. - See Details

- 2015-04-23 New approach could enable low-cost silicon devices in fibers that could be made into fabrics
- Scientists have known how to draw thin fibers from bulk materials for decades. But a new approach to that old method, developed by researchers at MIT, could lead to a whole new way of making high-quality fiber-based electronic devices.
The idea grew out of a long-term research effort to develop multifunctional fibersthat incorporate different materials into a single long functional strand. Until now, those long strands could only be created by arranging the materials in a large block or cylinder called a preform, which is then heated and stretched to create a thin fiber that is drastically smaller in diameter, but retains the same composition. - See Details

- 2015-04-23 Trial nears in high-profile Silicon Valley sex bias case
- A jury was picked Monday to determine whether a venerable Silicon Valley venture capital firm is liable in a sexual discrimination lawsuit or is the victim of a former employee forced out because of poor performance.

- 2015-04-23 Magnetic nanoparticles enhance performance of solar cells
- Magnetic nanoparticles can increase the performance of solar cells made from polymers - provided the mix is right. This is the result of an X-ray study at DESY's synchrotron radiation source PETRA III. Adding about one per cent of such nanoparticles by weight makes the solar cells more efficient, according to the findings of a team of scientists headed by Prof. Peter Müller-Buschbaum from the Technical University of Munich. They are presenting their study in one of the upcoming issues of the journal Advanced Energy Materials (published online in advance).

- 2015-04-23 Silicon micro-funnels increase the efficiency of solar cells
- The fovea centralis, or fovea for short, sits in the middle of the Macula lutea (or macula) of the retina, where the slender, funnel-like ocular cones are especially closely packed together. We see an image with greatest acuity in this small region because each cone there is connected to a nerve cell.
This closely packed arrangement of cones has now inspired the team headed by Prof. Silke Christiansen to replicate something similar in silicon as a surface forsolar cells and investigate its suitability for collecting and conducting light. - See Details

- 2015-04-22 Woman in Silicon Valley sex discrimination suit to testify
- The woman at the center of a sex discrimination lawsuit against one of Silicon Valley's most prestigious venture capital firms is set to take the stand in a case that has focused attention on the treatment of women in the high-tech and venture capital fields.
Ellen Pao says she was passed over for a promotion at Kleiner Perkins Caufield & Byers because she is a woman and was fired in 2012 after she complained. Pao's attorney, Alan Exelrod, has argued that Kleiner Perkins had a male-dominated culture where women were excluded from parties, asked to take notes like they were secretaries and subject to coarse behavior and harassment by their male colleagues. - See Details

- 2015-04-22 Largest-scale silicon photonic switch: Low loss optical design enables up to 2,500 switch elements on 1 x 1 cm chip
- Today's explosion of video and Internet data is driving unprecedented traffic demand within datacenters. With data transfer rates exceeding 100 gigabits-per-second (Gb/s), communication between servers requires optical switches with faster switching time (micro-to nano-second level), broader band operation, larger capacity for switching elements and lower energy consumption.
Researchers at the University of California, Berkeley have developed a novelsilicon photonic switch, which is the largest-scale and the lowest-energy loss switch reported to date. It features a switching time of sub-micro seconds and a broad bandwidth of hundreds of nanometers. - See Details
