PBPD-001 Polarization Diverse Balanced Photodetector

Polarization Diverse Photodetector; 1310, 1550 nm; Aluminium Enclosure; Signal Conversion Gain >30 V/mW; RF Bandwidth 0-210 MHz; Transimpedance Gain 3x104 V/A

OCT and sensor systems require high-performance balanced photodetectors to increase system signal-to-noise ratio (SNR). Polarization-sensitive OCT and similar applications require separate analysis of the two polarization components of a signal.

General Photonics’ PBPD-001 polarization diverse balanced photodetector module is specially designed for use in such systems and adds polarization sensitivity to the balanced photodetector circuitry of the BPD-002 or BPD-003 balanced photodetector modules.

The PBPD-001 polarization diverse balanced photodetector is fully enclosed in a compact, sturdy aluminium box with two optical input ports, a balanced RF output port and two monitor ports for each polarization component and a 12 VDC power supply port.

With a bandwidth up to 200 MHz, a transimpedance gain larger than 30K and a saturation power larger than 130 μW, the PBPD-001 polarization diverse balanced photodetector is ideal for integration into laboratory or commercial OCT, fiber sensor, and high performance optical measurement systems with polarization dependent detection requirements.
