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, …
Read More »There were 79 zettabytes of data generated worldwide in 2021. By 2025, more than 150 zettabytes of big data will need analysis. Dramatic increases in data storage capacities are urgently needed as they are being outpaced by exponential growth in data generation, driven by use of the internet, social media, …

A submarine is a naval platform that can stay underwater for an extended period to carry out missions, both offensive and defensive. It is a complex platform that includes multiple components. As radio waves cannot propagate in water, communication with submarines is difficult. To overcome this issue, submarines are being …

Driven by technology advances in solid-state optoelectronics, light-emitting diode (LED) lighting has been expanded to a wide range of applications in consumer electronics, automotive, architectural, and healthcare settings. Recently, there has been a drive to make lighting “smart” by incorporating internet of things (IoT) connectivity and machine learning-based artificial intelligence …

Nonlinear optics is a part of optics, dealing with various kinds of optical nonlinearities e.g. in nonlinear crystal materials (including both dielectrics and semiconductors) or in optical fibers and other waveguide devices. Nonlinear effects with light are those where e.g. twice the optical input intensities does not simply result in …

Switches are important components of any communications network. Switches are found inside network-connected devices and used to change data transmission paths when transmitting data between devices. By quickly changing the transmission pathway and sending data only to relevant devices, the total load on the network can be reduced. Optical …
Read More »Nonlinear optical (NLO) materials have long been known to interact with light, to produce a nonlinear response. Nonlinear optical materials use nonlinear dependence of the refraction index on the applied electric field to produce other frequencies. This results in either harmonic generation or frequency shifting. The development of the field was …
Read More »Muons are subatomic particles that behave a lot like electrons but are around 200 times heavier. As the US Department of Energy explains, “Muons created in the atmosphere constantly hit every inch of the Earth’s surface and pass through almost any substance.” Many scientists have noted that measuring the …
