    • Through its higher refractive index, a silicon grism can be used to reduce the Described herein are systems and methods for reducing optical aberrations in an optical system to decrease polarization dependent loss. Embodiments are provided particularly to define beam trajectories through an optical switching system which reduce off-axis aberrations. In one embodiment, a silicon grism is provided for reducing the curvature of the focal plane at an LCOS device in a wavelength selective switch (WSS) such that the separated polarization states converge at the LCOS at substantially the same point along the optical axis for all wavelengths. In this embodiment, an axial offset at the LCOS device will not produce large PDL at the coupling fibers. In another embodiment, a coupling lens having an arcuate focusing region is provided to address an offset in the optical beams, such that the separated polarization states couple symmetrically to respective output fibers.
    • 通过其更高的折射率,可以使用硅棱镜来降低。这里描述的是用于减少光学系统中的光学像差以减少偏振相关损耗的系统和方法。 特别提供了实施例来定义通过减少离轴像差的光学开关系统的光束轨迹。 在一个实施例中,提供硅棱镜用于降低波长选择开关(WSS)中的LCOS器件处的焦平面的曲率,使得分离的偏振态在所有的基于相同点的光轴处在基本相同的点处会聚 波长。 在该实施例中,在LCOS装置处的轴向偏移将不会在耦合光纤处产生大的PDL。 在另一个实施例中,提供具有弧形聚焦区域的耦合透镜以解决光束中的偏移,使得分离的偏振状态对称地与相应的输出光纤耦合。
