Over the past decade, the proliferation of fiber optic sensors and sensing systems has been ever-increasing, especially the use of fiber Bragg grating (FBG) based sensors. 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, …

Photonics is a breakthrough technology as it uses photons (smallest unit of light) as the data carrier instead of electrons (smallest unit of electricity) used in electronic ICs. As light travels very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed. Thus …
Read More »A graphics processing unit (GPU) is a specialized, electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. Modern GPUs are very efficient at manipulating computer graphics and image processing. GPUs were traditionally tasked …
Read More »An optical network is a communication system that uses light signals, instead of electronic ones, to send information between two or more points. The points could be computers in an office, large urban centers or even nations in the global telecommunications system. These include limited range local-area networks (LAN) or wide-area …
Read More »Infrared radiation detectors are a critical component for DoD imaging systems used in areas such as military vehicles, military night vision, military communication, environmental monitoring, and target acquisition. In addition, they are crucial for commercial markets including surveillance, digital cameras, automotive and scientific research. Common constraints for IR sensors …
Read More »Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of space. These waves have different wavelengths (the distance from wave crest to wave crest) and frequencies, These two are inversely related to each other, the shorter the wavelength, …

A spatial light modulator (SLM) is a special device that can manipulate light by modulating the amplitude, phase or polarization of the light waves in the two dimensions of space and time. This means that light is manipulated in order to obtain a desired output, and SLM is commonly used …
Read More »Photonics is the science of controlling the flow of light. The characteristics of the waves of light or individual photons that make up light can be used to explore the universe, cure diseases, and even solve crimes. It is a branch of optics that deals with the generation, transmission, modulation, …
