Kyocera Corporation (Kyoto, Japan) announced that its wholly owned subsidiary, Kyocera Crystal Device Corporation, in charge of development and manufacturing of crystal devices, has succeeded in developing a temperature characteristics-free etalon filter — a crystal device which has applied the atomic diffusion bonding technique. An etalon filter is a component which detects deviations in multiple light wavelengths in high-capacity optical communication transmissions systems. Its external dimensions are >1.2mm squared; its adaptive wavelength is 1,520 to 1,620nm; temperature characteristics: ±0.15pm /°C typ. (pm/°C = 10-12m/°C); FSR: 50/100 GHz; and custom extinction ratio or reflectance.
