Chip-Scale Visible Sources Aim to Release Quantum Technology from the Lab
The visible range, spanning around 380 to 700 nm, has longstanding use in photonics. Many materials have specific absorption, reflection, and transmission characteristics in this band, which are exploited for applications from optical metrology and biomedicine to quantum and communications. Increasingly stable and versatile visible lasers are populating the market, and the efficacy of these sources is intersecting with the emergence of chip-scale lasers — a burgeoning innovation
