We demonstatre a multiple star WDM-PON using BSWDM filter to serve several subscriber groups located at a widely distributed area. It enables to use a single type AWG for second RN and simplifies management issues.Show More
Integrated-optic waveguide devices become more and more complicated to realize high functionality. Optical functional devices are important to solve electrical bottleneck issues. Ultra-compact and CMOS compatible silicon waveguides are important for the integration of an optical component and an electronic circuit aiming at higher level of functionalities. This paper reviews the recent progress an...Show More
