Properties of planar lightwave circuit (PLC) devices fabricated by silica and silicone polymer

摘要

Recently, photonic networks based on wavelength division multiplexing (WDM) systems have developed considerably in response to the explosive growth of the Internet. Devices with novel functions are required for photonic networks, and planar lightwave circuits (PLCs) are being considered to meet this need. This paper reports recent progress on PLC-type devices with advanced functions developed for the photonic networks. We describe fabrication techniques and device applications for silica and silicone polymer based PLC technologies.
