Investigation of emerging technologies for use in Polarization Scramblers and Mode Converters

通过与卡尔顿大学的合作，Viavi解决方案公司希望改进他们现有的模式转换和极化干扰技术。模式转换技术允许增强对网络损耗的调节，并将提高光功率测量的可靠性。为了消除有害的极化依赖效应，如极化依赖损耗和极化模色散，在电信网络中需要极化加扰。我们将研究长周期光纤布拉格光栅的使用，这是卡尔顿研究人员具有相当专业知识的领域，用于模式转换。在另一项研究中，我们将研究新兴材料的可行性，如高Verdet常数玻璃或高度非线性光纤用于偏振扰频器。

Through a collaboration with Carleton University, Viavi solutions hopes to improve on their existing technologies for mode conversion and polarization scrambling. Mode conversion technologies allow for enhanced regulation of loss in the network and would improve the reliability of optical power measurements. Polarization scrambling is desirable in telecommunications networks in order to eliminate deleterious polarization dependent effects such as polarization dependent loss and polarization mode dispersion. We will be investigating the use of long period fiber Bragg gratings, an area in which Carleton researchers have considerable expertise, for use in mode conversion. In a separate study we will be investigating the feasibility of emerging materials such as high Verdet constant glasses or highly non-linear fiber for use in polarization scramblers.
