“…The film filters are commonly used as the wavelength-division (de)multiplexers in the optical communication systems [1][2][3][4], but such type of devices suffers from the difficulties in package and volume production, which make them expensive. Integrated waveguide based optical structures offer the possibility to miniaturize bulk optical functions and provide the possibility for future integration of the triplexer with optical sources and receivers.…”

Wavelength-division-multiplexing (WDM) transceiver filters are one of the most essential components for realizing the fiber-to-the-home (FTTH) networks. In recent years, silicon photonics have provided a very attractive platform to build ultra-compact photonic integrated devices with CMOS-compatible processes. In this review, we focus on the recent progresses on diplexers/triplexers based on multimode interference couplers (MMI), and directional couplers (DC). The polarization-insensitive devices are also discussed.

“…At every node of the systems, add/drop function is also needed for signal processing so such a node is named a reconfigurable optical add/drop multiplexer (ROADM). Optical switches and routing devices based on a planar lightwave circuit (PLC) have been studied but there still remain difficulties in handling a large number of spatial port counts [32][33][34]. A wavelength selective switch (WSS) is an alternative choice to realize such a functionality, which offers a much simpler way in routing the wavelengths.…”

We review a new type of dispersion elements based on a Bragg reflector waveguide, which provides a large angular dispersion of 1~2°/nm. The device functions as sub-wavelength virtually imaged phased array grating. We obtain a number of resolution-points (possible channel-count in demultiplexing) over 1,000. We demonstrate a large-scale wavelength switch based on a Bragg reflector waveguides array. The waveguides array has a small footprint of 2×4 mm 2 , but provides both ultra-large numbers (>100) of output-ports and wavelength-channels at the same time. Prospects for further increase in the wavelength channel count and output ports will be discussed.

“…Among these devices, a planar lightwave circuit (PLC)-based add/drop filter together with the combination of a MZI and a photoinduced Bragg grating [7] is suitable for constructing LAN's, because the PLC add/drop filter is a low-cost device due to its simple structure and easy mass-producibility. The device may be made even more compact and cost effective by utilizing hybrid integration of the laser diode or photo detector [8].…”
