Ana González and Antonio Raspa, European Photonics Industry Consortium (EPIC)

The increasing data traffic that has been stimulated by emerging services such as data center cloud services and 5G will require the use of technologies that can reduce power consumption, are cost-effective, and provide enhanced data security. In this context, the miniaturization provided by photonic integrated circuits (PICs) — small waveguides with nanometric dimensions — makes them the perfect technology to help achieve these results because they are fabricated on wafers using a standard complementary metal oxide semiconductor (CMOS) fabrication process. Additionally, lasers...Read full article

    nanophotonics
    Nanophotonics is a branch of science and technology that explores the behavior of light on the nanometer scale, typically at dimensions smaller than the wavelength of light. It involves the study and manipulation of light using nanoscale structures and materials, often at dimensions comparable to or smaller than the wavelength of the light being manipulated. Aspects and applications of nanophotonics include: Nanoscale optical components: Nanophotonics involves the design and fabrication of...
    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    quantum key distribution
    Quantum key distribution (QKD) is a method of secure communication that utilizes principles from quantum mechanics to establish a shared secret key between two parties, typically referred to as Alice and Bob, while detecting any potential eavesdropping attempts by a third party, commonly known as Eve. The fundamental principle behind QKD is the use of quantum properties, such as the superposition principle and the no-cloning theorem, to enable the distribution of cryptographic keys in a...
