The ability to observe events on such timescales is important for basic physics — to understand how atoms move within molecules — as well as for engineering semiconductor devices, and for understanding basic biological processes at the molecular level. Today, researchers can easily reach into the realm of femtoseconds — quadrillionths …

One of the biggest challenges for 5G and last mile 10 Gig deployments is not raw data speeds, but middle mile and core networks.  Currently, top speeds for core networks are between 200 Gbps and 400 Gbps, depending on the carrier and day of the week. Optical systems with advent …

Free Space Optical or Laser communications is creating a new communications revolution, that by using visible and infrared light instead of radio waves for data transmission  is providing  large bandwidth, high data rate, license free spectrum, easy and quick deployability,  low mass and  less power requirement. It also offers low …

Lidars (Light Detection and Ranging) are similar to radars in that they operate by sending light pulses to the targets and calculate distances by measuring the received time.  The  key advantages of  LIDAR is  its superior accuracy and its ability to see through masking items, such as leaves, trees, and …

The Laser Directed Energy Weapons (DEWs) offer a transformational ‘game changer’ to counter asymmetric and disruptive threats, while facing increasingly sophisticated traditional challenges. Laser technology provides major advantages for military applications over kinetic weapons due to High precision and rapid on-target effect, precise and scalable effects,  avoidance of collateral damage …

Smart glasses refer to wearable computing devices that add information to what the user sees. These devices function in a way similar to mobile phones and tablets and have the ability of processing and implementing various programs and applications. A majority of the smart glasses currently used in the market …

Optical atomic clocks are at the pinnacle of time measuring devices, losing less than one second every ten billion years. Currently though, they are massive devices, weighing hundreds of kilograms. In order to have an optimal practical function that could be utilised by your average person, their size needs to …

The quantum cascade laser is a special kind of semiconductor laser, usually emitting in the mid- and long-wave infrared bands. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure.  Their wide tuning range and fast response time allow for faster …

The fiber optic sensors also called as optical fiber sensors use optical fiber or sensing element.  These Sensors can measure a large variety of parameters, such as temperature, pressure, strain, refractive index, vibrations, displacements, bending, loading, and liquid level or concentration of chemical species.   Over the past decade, optical …
