Wearable Photonic devices technology and Flexible stretchable Optical sensors

Currently, old-style personal Medicare techniques rely mostly on traditional methods, such as cumbersome tools and complicated processes, which can be time-consuming and inconvenient in some circumstances. Furthermore, such old methods need the use of heavy equipment, blood draws, and traditional bench-top testing procedures. Invasive ways of acquiring test samples can …

Optical Networks Vulnerabilities and Security threats

Optical networks are vulnerable to several types of security breaches or attacks, typically aimed at disrupting the service or gaining unauthorized access to carried data, i.e., eavesdropping. Depending on the aim of the attack, security breaches can induce financial losses to the clients or cause network-wide service disruption, possibly leading to huge …

Military applications of Ultravoilet spectrum becoming feasible with Technology breakthroughs

The electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays. As the wavelength of the electromagnetic radiation shortens, the waves have a higher frequency—how quickly electromagnetic waves follow each other—and therefore more energy.   Ultraviolet (UV) is electromagnetic radiation with …

Quantum Imaging technique can have military applications, US and China racing to deploy quantum ghost imaging in satellites for stealth plane tracking

Today, we are witnessing the second quantum revolution, where quantum states, which can exhibit superposition and entanglement, are harnessed for quantum technological applications. Quantum Sensing exploits the high sensitivity of quantum systems to external disturbances to develop highly sensitive sensors.   Breaking the limitations of today’s established imaging schemes is a …

Inverse design in photonics

The design of digital circuits is currently dominated by hardware description languages such as Verilog and VHDL. This automation of circuit design has enabled the development of modern computer processors with billions of transistors.   Integrated photonic devices, on the other hand, are still designed by hand. A designer first picks …

Global Fiber Optic Cable Market

Fiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. We rely on them to transmit light signals over long distances.   Optical fibers typically include a glass structure called core …

Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

Materials for nonlinear integrated photonics

Nonlinear optics (NLO) is the branch of optics that describes the behavior of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. The nonlinearity is typically observed only at very high light intensities (values of the …

Vertical-cavity surface-emitting lasers (VCSEL& VECSEL) arrays enable data communication to lidar and military infrared imaging

The illumination source employs different technologies, ranging from lamps to semiconductor light emitting diodes (LEDs) or lasers. The lamp, while straight-forward, is broad-band, bulky, and generally inefficient.   The main wavelengths of interest for illumination are around 808nm, 976m, 1064nm, and 1550nm. The 808nm region offers the best responsivity for …
