InGaAs FC Fiber Balanced Photoreceiver, 900-1700nm

• Subtracts Two Photodiode Signals for Differential Detection
• Improved Signal to Noise Ratio (SNR) for Weak or Modulated Optical Signals
• High Common-Mode Noise Suppression for Improved Measurement Sensitivity and Accuracy
• Available in Si and InGaAs models for UV-VIS and NIR spectral ranges

Balanced Photoreceivers use true differential detection by subtracting the photocurrents from two matched photodiodes, producing a single electrical output proportional to the difference in optical power between the two inputs. This suppresses common-mode noise, such as laser intensity fluctuations, improving SNR and measurement sensitivity. Balanced Photoreceivers are engineered with a low-noise transimpedance amplifier, which ensures stable, consistent performance for precision optical measurements. Available in Si and InGaAs models for UV-VIS (320-1000nm) and NIR (800-1700nm) spectral ranges, these photoreceivers are ideal for coherent optical detection, interferometry, spectroscopy, and optical coherence tomography (OCT).
