Lasers: The most well-known coherent source is probably the laser. They discharge powerful, tightly focused light waves that have a defined phase connection. Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into ... We demonstrate a new optical technique that converts light from a sparse array of mutually coherent sources into a single-lobed far-field with a theoretical ...
