Low-cost avalanche photodiode comes in an M1 package

Low-cost avalanche photodiode comes in an M1 package
LASER COMPONENTS has announced that its cost-effective SAH series of avalanche photodiodes (APDs) is now available in an M1 package. This is the smallest available SMD housing (Surface-Mounted Device), at only 2 mm x 1.4 mm. The new APDs will be presented at SPIE DCS in Orlando, Florida (Booth 1029). Optimised for wavelengths of 850 nm and 905 nm, these components are mainly designed for range finding applications in which larger detectors cannot be installed due to lack of space.

Imaging technique pulls plasmon data together

Imaging technique pulls plasmon data together
Rice University scientists have developed a novel technique to view a field of plasmonic nanoparticles simultaneously to learn how their differences change their reactivity. Their new method is called snapshot hyperspectral imaging (SHI), which up to now has been used primarily in astronomy. SHI allows researchers to view minute differences between otherwise identical nanoparticles and see how they react in response to light and environmental changes.

Latest line-up of high speed signal transmission photorelays

Latest line-up of high speed signal transmission photorelays
Toshiba Electronics Europe has announced the launch of two high speed signal transmission photorelays that offer the industry’s smallest footprint. The TLP3475S features low on-state output resistance (RON) – typically 1.1Ω and offers fast switching times of 0.5ms (ton) and 0.4ms (toff). The device is rated for 60V (VOFF) and a max. current of 0.4A (ION). The device is housed in an S-VSON4 package measuring just 2.00mm x 1.45mm x 1.65mm.

Super-resolution microscopy in space and time

Super-resolution microscopy in space and time
Super-resolution microscopy is a technique that can “see” beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest recently, especially since its developers won the Nobel Prize in Chemistry in 2014. But super-resolution microscopy comes with a big limitation: it only offers spatial resolution.

Boost efficiency and stability of optical rectennas

Boost efficiency and stability of optical rectennas
The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements could allow the rectennas – which convert electromagnetic fields at optical frequencies directly to electrical current – to operate low-power devices such as temperature sensors.

Optimising optics through increased design efficiency

Optimising optics through increased design efficiency
If photonics is to meet the needs of a new generation of applications, problems will need to be addressed through better design and modelling. The EU-funded ADOPSYS project approached this challenge as much with a skills-based answer, as a technical one. Currently the field of photonics suffers from a lack of broad expertise in applied modelling and design for industrial optical systems and components.

Hyperlens crystal views living cells in unprecedented detail

Hyperlens crystal views living cells in unprecedented detail
Just imagine: An optical lens so powerful that it lets you view features the size of a small virus on the surface of a living cell in its natural environment. Construction of instruments with this capability is now possible because of a fundamental advance in the quality of an optical material used in hyperlensing, a method of creating lenses that can resolve objects much smaller than the wavelength of light.
