Abstract: Techniques for bonding a luminescent material to a thermally conductive substrate using a low temperature glass to provide a wavelength converter system are provided. A dichroic coating is deposited on a thermally conductive substrate. The dichroic coating includes alternating layers of a first material having a first refractive index and a second material having a second refractive index which is greater than the first refractive index. A buffer layer is deposited on the dichroic coating. A wavelength converter is bonded to the buffer layer by a layer of low temperature glass. In some embodiments, the wavelength converter includes a phosphor for converting a primary light from an excitation source into a secondary light.
