More Information
Summary:An optical device (102) configured for concentrating light towards a target element (104) is provided. The optical device (102) comprises a waveguide element (106) configured for guiding light towards the target element (104), and a wavelength conversion element (108) configured for converting incoming light of a first wavelength into outgoing light of a second wavelength. The wavelength conversion element (108) extends adjacent to the waveguide element (106). An interface (114) between the waveguide element (106) and the wavelength conversion element (108) comprises a surface roughness. The latter may provide for an increased efficiency and low manufacturing costs of the optical device (102).
