Any Color You Like: NIST Scientists Create 'Any Wavelength' Lasers

NIST scientists have developed integrated photonics circuits by depositing complex material patterns onto silicon wafers, enabling lasers to be produced at any wavelength. The chips integrate optical devices (lasers, waveguides, filters, switches) to process information using light instead of electrons. The work, published in *Nature*, could accelerate AI acceleration hardware, quantum computing, and optical atomic clocks.
