我们设计了一个由偏振分束器和偏振旋转器组成的具有偏振分集的硅光子电路。分束器采用简单的定向耦合器，旋转器采用离轴双芯结构。这两种器件都可以通过使用平面制造技术来制造，并且不需要复杂的三维结构制造工艺。作为偏振分集的一个应用，我们制作了一种基于硅线波导的偏振无关波长滤波器。该滤波器由偏振分束器、旋转器和环形谐振器组成。滤波器的偏振相关损耗约为1dB。一个10-Gbps的数据传输与扰频极化。(C)2008年美国光学学会。
We devised a silicon photonic circuit with polarization diversity that consists of polarization splitters and polarization rotators. The splitter is based on a simple directional coupler and the rotator has an off-axis double-core structure. Both devices can be made by using planar fabrication technology and require no complex proceses for the fabrication of three-dimensional structures. We fabricated a polarization-independent wavelength filter based on Si wire waveguides as an application of the polarization diversity. The filter consists of the polarization splitters, the rotators, and a ring resonator. The polarization-dependent loss of the filter is about 1 dB. A 10-Gbps data transmission with scrambled polarization is demonstrated. (C) 2008 Optical Society of America.
