Kyocera Develops Crystal Etalon Filter for WDM

Kyocera has developed a new Crystal Etalon Filter technology that prevents dense wavelengths of light from interfering with each other by sensing deviations between multiple wavelengths. The new product, which was created by Kyocera Kinseki, is able to assign arbitrary figures as a wavelength temperature coefficient ranging from 5.4 to 15.7pm/˚C. The company says this enables more flexibility in designing tunable laser modules, while contributing to higher precision, and better wavelength stability and reliability. http://www.kyocera.com
