Visible wavelengths are getting increasing attention due to their usefulness for communication, quantum, and sensing applications. In communication, blue-green wavelengths can be used for underwater comm, while LiFi systems can work across the visible spectrum. Visible wavelengths are often necessary when probing physical systems, such as the neutral atoms or ions used in quantum computing and optical clocks or the color centers used in quantum sensors; or biological systems as in medical or chemical sensors. Visible light can also be useful for lidar and atmospheric sensing. Finally, nonlinear photonics and frequency combs often involve visible wavelengths.  

This special session will begin by covering mature and emerging applications of visible light photonics. It will address why visible light is needed and what the benefits are compared to working in the more traditional telecommunication range. It will also explain how mature the current applications are and what systems, if any, are used in the field. It will then cover the state of the art of visible light devices such as lasers, detectors and fibers, as well as foundry processes and packaging needs. Here the maturity of the available technologies and whether current or anticipated future performance is acceptable for application needs will be addressed. The session will also attempt to highlight what the largest outstanding needs are in this emerging field.
