Polarization-Maintaining Fiber Axis Finding Method

We propose a simple method to measure the total rotation of polarization axis in PMFs caused by both internal and external rotation. The method is suitable for any kind of PMF, and avoids the additional cl. [pdf]

Energy-efficient Nicaraguan arrayed waveguide grating for IDC data centers

Arrayed waveguide gratings (AWG) are commonly used as in (WDM) systems. These devices are capable of many into a single, thereby increasing the capacity of considerably. The devices are based on a fundamental principle of, which states that of different wavelengths linearly with each other. This means that, if each in an. [pdf]
