Cierra Photonics Develops Thin-film Deposition Process for Optical Filters

Cierra Photonics, a start-up based in Santa Rosa, California, introduced its third generation Advanced Energetic Deposition, a thin-film deposition technology that enables rapid, high uniformity optical coatings to be grown on wafers. The technology is especially applicable for making optical filters for CWDM and FTTH applications. Cierra is using the technology for a line of 100, 50 and 25 GHz thin-film filters.
