Frequency-modulated coherent lidar promises to collect more of the data computers need to drive cars—the challenge is to bring down costs and improve performance.
In the early 1990s, when I attended my first technical sessions at CLEO, I was not surprised that the audience was overwhelmingly male. That was a long time ago and, thankfully...
Programmable self-assembly of nanoparticle patterns enables a low-cost platform for nanoscale to mesoscale structures such as life-science substrates, custom diffraction gratings...
An all-optical-fiber coupled-cavities quantum electrodynamics (QED) system demonstrates a reversible interaction between atoms and photons separated by 2 m of fiber—an important...
Dual-depletion region InGaAs photodiodes have a radiation-hardened architecture that qualifies them for the rigors of lidar, communications, and referencing systems in space-based...
With LED pumping of only 14 W/cm2 peak power, an acousto-optically Q-switched Nd:YLF laser produces pulses with duration of 452 ns and energy of 10.6 μJ.
Fabrication of aspheric microlens arrays through direct cutting or grinding methods can be expensive and limited to small batches; a new off-axis spindle grinding method forms...
A circuit analog of time-resolved microwave reflectance using an RF-concentrating resonator amplifies the response to optical excitation of a small volume of optoelectronic material...
Matching two QKD entangled photons’ wavelengths to the right parts of the fiber dispersion curve for two fiber routes allows both photons to arrive simultaneously.
By illuminating a mixture of polymers with different wavelengths of light in a pre-determined spatial and temporal pattern, standard vat polymerization can build a multimaterial...
Editor in Chief John Lewis celebrates the life of Andrew Charles Wilson, his impact on machine vision and imaging, and introduces Laser Focus World’s May 2019 issue, which includes...
