OPTICAL WAVELENGTH CONVERTER AND COMPOSITE OPTICAL DEVICE
To provide an optical wavelength converter and a composite optical device, each of which exhibits excellent heat dissipation property and superior optical wavelength conversion characteristics. An optical wavelength converter 1 is configured such that an optical wavelength conversion member 9 is bonded to a heat dissipation member 13 having superior heat dissipation property. Thus, heat generated by light incident on the optical wavelength conversion member 9 can be efficiently dissipated. Therefore, even when high-energy light is incident on the optical wavelength converter, temperature quenching is less likely to occur, and thus high fluorescence intensity can be maintained. An intermediate film 21 is disposed between a reflective film 19 and a bonding portion 15. The presence of the intermediate film 21 improves the adhesion between the reflective film 19 and the bonding portion 15, thereby enhancing the heat dissipation from the optical wavelength conversion member 9 to the heat dissipation member 13. Thus, the temperature quenching of the optical wavelength conversion member 9 can be prevented, thereby enhancing fluorescence intensity.
