Caltech News
Pointing Light Toward Faster Optical Communications
PASADENA, Calif., Dec. 10, 2012 — A device that focuses light into a point just a few nanometer across could lead to more efficient optical devices and higher-resolution imaging systems.
New Solar Research Facility Breaks Ground
BERKELEY, Calif., Oct. 29, 2012 — Construction has begun on a 40,000-sq-ft solar energy research facility at Lawrence Berkeley National Laboratory that will aid in the quest for alternative fuels from sunlight.
Microscale Optical Accelerometer Engineered
PASADENA, Calif., Oct. 24, 2012 — An ultrasensitive, miniature optical accelerometer uses laser light rather than electrical circuits to gauge movement, a change that could transform the microelectronics industry, its creators say.
Light Focused Deep Inside Tissue
PASADENA, Calif., June 28, 2012 — A new procedure that is as simple as an ultrasound more than doubles the depth that light can be focused inside biological tissues and soon could enable doctors to perform incision-free surgery or to diagnose cancer by seeing tumors inside the body.
Nanophotonic Solar Research Wins Energy Prize
PASADENA, Calif., and AMSTERDAM, May 24, 2012 — Albert Polman and Harry Atwater received the ENI Renewable and Non-conventional Energy Prize 2012 for their research on high-efficiency solar cells based on nanophotonic design.
Full spectrum boosts solar cell power
May 1, 2012 — Solar cell efficiency, currently hovering in the 15 to 20 percent range, can theoretically be boosted to as high as 70 percent by printing specially engineered nanostructures on the cells, researchers say.
First Light of Mosfire Celebrated
WAIMEA, Hawaii, April 12, 2012 — The Mosfire instrument observed the universe with its near-infrared sensing eyes for the first time on April 4, capturing images of a pair of interacting galaxies known as The Antennae. The new device will enable astronomers to study space phenomena...
Full Spectrum Boosts Solar Cell Power
PASADENA, Calif., Feb. 29, 2012 — Solar cell efficiency, currently hovering in the 15 to 20 percent range, can theoretically be boosted to as high as 70 percent by printing specially engineered nanostructures on the cells, researchers say.
Data Transfer Hits Record of 186 Gb/s
PASADENA, Calif., Dec. 15, 2012 — With a sustained data transfer rate of 186 Gb/s, a new world record has been set, ushering in the next generation of high-speed network technology. At the SuperComputing 2011 conference in Seattle in mid-November, an international team of...
Smart petri dish analyzes cell growth
PASADENA, Calif. — Built from a smartphone, a commercially available cell phone image sensor and some Lego blocks, ePetri isn’t like other petri dishes. The compact, lens-free microscopy imaging platform can track cell cultures and bacteria as they incubate....
Object Cooled to Quantum Ground State with Laser Light
PASADENA, Calif., Oct. 12, 2011 — California Institute of Technology (Caltech) researchers, in collaboration with a team from the University of Vienna, have cooled a miniature mechanical object to its lowest possible energy state — its quantum ground state — using laser...
Light isolated on photonic chips for next-gen computing
PASADENA, Calif. – A new technique that isolates light onto a photonic chip could pave the way for faster computers and reduced data loss when connected to the global fiber optic network. California Institute of Technology scientists have designed an optical...
Kaul to Lead EPMD Program at NSF
ARLINGTON, Va., Sept. 23, 2011 — Dr. Anupama B. Kaul has joined the National Science Foundation’s Electrical, Communications and Cyber Systems Div. as its new program director in Electronics, Photonics and Magnetic Devices (EPMD), the foundation announced. Kaul comes to...
Light Isolated on a Photonic Chip
PASADENA & SAN DIEGO, Calif., Aug. 5, 2011 — Information systems increasingly are relying on fiber optic networks carrying data via photons instead of electrons, but computer technology still relies heavily on electronic chips, which are slower and more prone to data loss than photonic chips....
Live-Imaging Technique Goes Sharper, Deeper, Faster
PASADENA, Calif., July 29, 2011 — Researchers from the California Institute of Technology have developed a novel approach that could redefine optical imaging of live biological samples by simultaneously achieving high resolution, high penetration depth and high imaging speed. ...
Student Innovators Improve Imaging
TROY, N.Y., and PASADENA, Calif., March 15, 2011 — The latest winners of the Lemelson-MIT Rensselaer Student Prize have been named, with prizes going to students using terahertz technology at Rensselaer Polytechnic Institute (RPI) and California Institute of Technology (Caltech). Benjamin...
Townes Receives Honorary Doctorate of Science
GLASGOW, Scotland, Feb. 8, 2011 — A Nobel prize-winning pioneer in laser technology has received an honorary degree from the University of Strathclyde in Glasgow, Scotland. Professor Charles Townes, of the University of California at Berkeley, received the Honorary Doctorate...
DiCon, Caltech Customize LHC Optical Switches
RICHMOND, Calif., Jan. 21, 2011 — The Large Hadron Collider (LHC) operated by CERN (European Organization for Nuclear Research) is the world’s largest particle accelerator. Stretching 17 miles long at its location near Geneva, the scientific instrument boosts protons to nearly...
Let It Snow!
Jan 1, 2011 — Crystals show up everywhere in the photonics world and are vitally important to the laser and optics fields in particular. But crystalline silica, sapphire and other materials are not as fragile and transitory as water ice crystals: snow. People...
Four-fold Quantum Memory Demonstrated
PASADENA, Calif., Dec. 3, 2010 — Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories. Their work also demonstrated a quantum interface between the atomic...
Lasers Used to ’Hear’ Ripples in Space
PASADENA, Calif., Nov. 30, 2010 — A new system of lasers is being tested that would “hear” gravitational waves, or ripples in space and time, while flying aboard the proposed space mission called Laser Interferometer Space Antenna (LISA). The research team, consisting of...
Yariv Awarded National Medal of Science
PASADENA, Calif., Nov. 2, 2010 — An innovator in the field of optoelectronics, Amnon Yariv has been named one of 10 recipients of the National Medal of Science, the highest honor bestowed by the US government on scientists. He is the Martin and Eileen Summerfield Professor of...
Broadband Pioneer Awarded Honorary Degree
GLASGOW, England, Oct. 13, 2010 — A Nobel laureate who helped create the technology that made the Internet possible has been presented with an honorary degree by the University of Strathclyde in Glasgow. Charles Kao received the Nobel Prize for Physics in 2009 for his...
Instruments Chosen for Mars Mission
WASHINGTON, August 16, 2010 — NASA and the European Space Agency (ESA) have selected the scientific instruments for their first joint mission to Mars. Scheduled for 2016, it will study the chemical makeup of the Martian atmosphere, including methane. Discovered on the red planet...
