Fotonipohjaisiin

Fotonipohjaisiin translates from Finnish to English as "photon-based." This term generally refers to technologies, systems, or processes that utilize photons, which are elementary particles of light and electromagnetic radiation, as their fundamental component or mechanism. This can encompass a wide range of applications and research areas.

In optics and photonics, photon-based systems are central. This includes lasers, which produce coherent beams of photons, and photodetectors, which convert photons into electrical signals. Fiber optics, used for high-speed data transmission, relies on the propagation of photons through optical fibers. The development of photon-based computing, or photonic computing, aims to use photons instead of electrons for computation, potentially offering advantages in speed and energy efficiency.

Beyond these core areas, photon-based principles are found in imaging technologies, such as digital cameras that capture photons using image sensors. Spectroscopy, the study of how matter interacts with light, is inherently photon-based, analyzing the absorption or emission of photons at different wavelengths. In quantum physics, photons are crucial for understanding phenomena like quantum entanglement and are the basis for quantum communication and quantum cryptography. The term highlights the reliance on light particles for the operation or function of a given technology.
