Since 1980 the research and development of PLC (planar lightwave circuit) devices using silica glass waveguides has been conducted.
As a result of the continuing development of this technology we have realized the mass production of PLC devices for optical communications
and optical signal processing with high performance and high reliability.
We will continue to support photonic network innovations by developing new PLC devices.
