The solar-blind properties of lanthanum aluminate (LaAlO3), as well as its large bandgap energy of 5.6 eV, make it a good candidate material for deep-UV photodetectors.
Phase-only computer-generated holograms generated by spatial light modulators (SLMs) can be used to diffract an incoming coherent beam into numerous focused spots distributed ...
Wideband antireflection (AR) coatings—those for which the ratio of the upper wavelength limit to the lower wavelength limit is greater than 2—are difficult to fabricate, especially...
A theoretical proposal by scientists at JILA (which is jointly operated by the National Institute of Standards and Technology and the University of Colorado, both in Boulder, ...
Researchers at Klastech (Dortmund, Germany) have developed the first continuous-wave (CW) all-solid-state ruby laser at 694.3 nm, with an output power of greater than 100 mW—the...
A laser-diode-simulation software package introduced by Nonlinear Control Strategies (NLCSTR; Tucson, AZ) is quite a bit more intricate than the laser-diode modeling software ...
Because diffraction limits the resolution of conventional photolithography to roughly one-quarter of the wavelength of light used, alternate techniques such as nanoimprint lithography...
Researchers at the University of California, Los Angeles (UCLA; Los Angeles, CA) have developed a real-time camera using a serial time-encoded amplified imaging technique that...
The European Space Agency has demonstrated that design detail and beam correction can enable high-power laser diodes to deliver efficient illumination with superior brightness...
While the benefits and detriments of sunlight have been known for decades, researchers are showing that electromagnetic radiation can be the key to safe and effective medical ...
Three super-giant ground telescopes planned to begin operation in 2018 have apertures two to four times larger than today’s biggest optical instruments.
Doped ceramic is the gain material of the future for many forms of diode-pumped solid-state lasers: if fabricated correctly, a ceramic gain material can have the transparency ...
Researchers at the University of Cincinnati and Sun Chemical (both in Cincinnati, OH) have developed a lithographically fabricated electrofluidic display that uses visually brilliant...
Because its probe and reference beams follow the same path, a common-path interferometer can measure changes in optical phase while being mostly unaffected by ambient variations...
A highly sensitive and frequency tunable terahertz detector based on carbon nanotube quantum dots is the main ingredient for a near-field terahertz imaging system in which all...
While routing femtosecond pulse energy to a broadband spectrum in optical fibers is important, many emerging nonsupercontinuum applications require selective routing of the pulse...
High-energy, ultrashort-pulse ultraviolet lasers are useful for many practical applications—for example, fabrication of solar cells and flat-panel displays, 3-D information storage...
