Abstract
We present a silica-based bidirectional arrayed waveguide grating router (AWGR) chip with cascaded optical switches intended for coarse wavelength-division-multiplexing (CWDM) applications. It performs multiple functions including multi/demultiplexing, switching and wavelength routing within a compact chip size. For uplink signal, we achieved a 1 dB optical bandwidth of more than 15 nm while for downlink signal, a 3 dB optical bandwidth of 12 nm was attained. The cascaded extinction ratios of optical switches are all above 30 dB across a large wavelength range. The results demonstrate its promising potential for flexible and cost-effective CWDM systems.
期刊介绍：
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
