Abstract
A system may have a window. The window may have a waveguide that includes photoluminescent material such as a phosphor layer. The waveguide may have a waveguide core surrounded by cladding layers. The waveguide may be located between an outer structural glass layer and an inner structural glass layer. A light source such as an ultraviolet light source provides pump light to one or more edges the waveguide. The pump light is guided within the waveguide and excites the photoluminescent material. This causes the photoluminescent material to luminesce and create visible light illumination. The visible light illumination may be used to light up an interior region of the system.
