POLARIZATION
DIVERSITY DETECTOR - PDD-001
|
|
Product Summary
Simultaneously detecting the power 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-001) 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.
