Balanced Photodetectors

Symmetrical Detectors and Interferometers with Integrated Detectors

Symmetrical InGaAs photodetectors, also referred to as balanced detectors, are used in fiber-optic applications in optical coherence tomography and fiber sensor technology. Mach Zehnder interferometers are also available with integrated symmetrical detectors.

Different models are available as balanced detectors:

• BPD-002 – Balanced Photodetector
  The BPD-002 model is characterized by easy handling and high performance and is designed for applications in research and development. This symmetrical receiver is fully housed and, therefore, suited for both laboratory and commercial applications in optical coherence tomography and fiber sensor technology.
• BPD-003 – Balanced Photodetector
  OEM version of the symmetrical photodetector that is integrated into measurement systems and used in optical coherence tomography and fiber sensor technology.
• PBPD-001 – Polarization Diverse Balanced Photodetector
  With this module, the polarization of the optical signal can also be determined. This device features a large bandwidth.
