Photonics

polaritonics

Between electronics and photonics there exists a frequency gap of approximately two octaves, i.e., the frequency range between 100 GHz and 10 THz, across which there are limited capabilities for signal generation, control, guidance, and processing. Researchers have demonstrated e that phonon-polaritons in ionic crystals like LiNbO3 or LiTaO3 may …

Novel LIDARs for 3D mapping, Driverless vehicles, Battlefield Visualization, Mine Hunting, and Imaging through forests

Remote sensing means that we aren’t actually physically measuring things with our hands. We are using sensors that capture information about a landscape and record things that we can use to estimate conditions and characteristics. LiDAR, or light detection ranging (sometimes also referred to as active laser scanning) is one …

DARPA GRYPHON developing high-performance microwave frequency source based on integrated photonics

In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars. The current tendency is to use carriers in higher frequency bands, especially with looming bandwidth bottlenecks due to demands for e.g. 5G and the “Internet of Things.” “Microwave …

Laser Technology Market

Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with highly …

Non-Line-of-Sight Imaging can be transformative in medicine, robotics, manufacturing, and security

We see things because our eyes are sophisticated light detectors: they constantly capture the light rays bouncing off nearby objects so our brain can construct an ever-changing impression of the world around us. Similarly in  a camera, All the light traveling from the object enters a single lens before it …

Twisted light can provide 100-times faster fiber capacity and secure wireless data transmission to moving platforms like UAVs

Broadband fiber-optics carry information on pulses of light, at the speed of light, through optical fibers. But the way the light is encoded at one end and processed at the other affects data speeds. Basically, light or any other electromagnetic radiation has energy defined by its frequency and momentum defined by …
