INSTRUMENTS SPECIAL POLARIZATION ACCESSORIES COMPONENTS APPLICATION FAQS GUIDE TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES - 84- General Photonics Corporation 909.590.5473 http://www.generalphotonics.com Simultaneously detecting the powers of two orthogonal polarization components is important for many sensor and measurement applications. A pigtailed polarization beam splitter coupled with two photodetectors can be used for such applications; however, this arrangement is bulky, troublesome to handle, and costly. By integrating polarization-splitting components with photodetectors, General Photonics created this compact device, which can be easily mounted onto a circuit board for customer applications. This Polarization Diversity Detector (PDD) features high detection sensitivity, high extinction ratio, high reliability, small size, and low cost. Once again, General Photonics leads the pack in providing solutions to customers’ needs.
