DARPA’s LUMOS to develop Photonic integrated circuits (PICs) and photonics platforms for defence applications

LUMOS

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 at very high speeds, photonics is widely used to…...

New efficient, high brightness, and tunable Quantum cascade laser (QCL)s technologes from mid-wave infrared (MWIR) to Terahertz region promise chemical warfare agents & hidden explosives detectors, to infrared countermeasure (IRCM) systems

QCLtech

Compact, chip-based lasers have conquered much of the electromagnetic spectrum, from ultraviolet to infrared, enabling technologies from digital communications and barcode readers to laser pointers and printers. Diode lasers depend on the process of electron-hole recombination: an electron from the…...

Graphene enables room temperature single photon emitter and detector for unhackable Quantum Key Cryptography (QKD)

QKDsingle

Quantum Key Distribution, or QKD, enables two remote parties, “Alice” and “Bob”, who are connected by a passive optical link to securely generate secret key material. Single-photon sources (SPSs) and single-photon detectors (SPDs) are key devices for enabling practical quantum key…...

Optical Circulators are building blocks for chips for optical communication networks and quantum computers

opticalcirculator

Fiber optical circulators are used to separate optical signals that travel in opposite directions in an optic fiber in order to complete bidirectional transmission. Optical circulators are also known as non-reciprocal optics, which means when the light travels in the…...

Hollow-core optical fibers enable secure communications in data centers, accurate sensing gyro for Aerospace applications

evolution of optical fibers 13 638

Conventional optical fibers are fabulously successful, but they have profound limitations. They contain a glass core at the center of the fiber through which light is transmitted. However, not only does this glass center limit the speed of the light…...
