Definitions

1. The field dedicated to the study and application of light waves involves the generation, manipulation, and detection of photons, impacting technology across various sectors like telecommunications and laser systems
2. Encompassing the science of light waves, this domain focuses on generating, controlling, and detecting photons, which is essential for advancements in optical communication and numerous technological applications
3. The discipline that explores the properties and behavior of light, focusing on the creation, control, and detection of photons, is crucial for innovations in communications and imaging technologies

Etymology: The word "photonics" is a modern coinage, built in English from "photon" and the suffix "-ics," which marks a branch of knowledge (as in physics, optics, mathematics). "Photon" itself comes from Greek "phōs," meaning light, and was adopted into physics in the early twentieth century for the quantum of light energy. Scientists then needed a name for the field devoted to that particle and its applications, so they added the familiar "-ics" to make a parallel to older sciences like optics. The suffix does much of the work here. "Optics" and "physics" both end in "-ics" because the Greek-derived ending was used to name systematic studies, and English speakers kept extending it to new fields. "Photonics" thus means something close to "the study of photons," though in practice it covers the generation, control and detection of light for technologies such as fibre-optic communication and lasers.
