摘要

我们提出了一种基于硅的双向阵列波导光栅路由器（AWGR）芯片，该芯片具有级联光开关，用于粗波分复用（CWDM）应用。它执行多种功能，包括多/解复用，开关和波长路由在一个紧凑的芯片尺寸。对于上行信号，我们实现了超过15nm的1db光带宽，而对于下行信号，我们实现了12nm的3db光带宽。在较大的波长范围内，光开关的级联消光比均在30db以上。结果表明，它在灵活、经济的CWDM系统中具有很大的潜力。

Compact Multifunctional CWDM Arrayed Waveguide Grating Router Cascaded With Optical Switches

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.
