Ceramic Wavelength Converter Having a High Reflectivity Reflector
There is herein described a ceramic wavelength converter having a high reflectivity reflector. The ceramic wavelength converter is capable of converting a primary light into a secondary light and the reflector comprises a reflective metal layer and a dielectric buffer layer between the ceramic wavelength converter and the reflective metal layer. The buffer layer is non-absorbing with respect to the secondary light and has an index of refraction that is less than an index of refraction of the ceramic wavelength converter. Preferably the reflectivity of the reflector is at least 80%, more preferably at least 85% and even more preferably at least 95% with respect to the secondary light emitted by the converter.
