Overview

The 80 MHz Large Area Adjustable Gain Balanced Photoreceivers are effective in reducing common-mode noise so that you can see your small signal. With a well-balanced combination of gain, bandwidth, and low noise, these photoreceivers are extremely flexible and are ideal for coherent heterodyne-detection applications including doppler LIDAR and optical coherence tomography.

Features

Reduces Common-Mode Noise by 25 dB

Balanced photoreceivers work by subtracting the photocurrent from two well-matched photodetectors. Common-mode noise that is present on both the reference and signal beams (such as laser intensity noise) is cancelled out and doesn’t appear as part of the signal. Any imbalance between the photocurrents generated by the reference and signal photodetectors, whether intentional or unintentional, is amplified and is seen as the signal. This reduces common-mode noise by up to 25 dB so that you can see your signal.

High Gain and Low Noise

The 80 MHz Balanced Photoreceivers feature high gain of up to 40V/mA while maintaining very low noise.

Ideal for Balanced Photodetection

Newport's balanced optical receivers are ideal for optical detection applications that require sensitive measurements and increased signal-to-noise. Balanced photodetection is a method that can very effectively cancel common mode noise and detect small signal fluctuations on a large DC signal. Detection methods in the time domain (such as femtosecond ultrasonics and frequency modulation spectroscopy) and frequency domain (like absorption spectroscopy), and coherent heterodyne detection (such as optical coherence tomography) can be substantially improved by using Newport balanced photoreceivers and can allow detection of signals not otherwise possible with other means. For more information, please see our application note A Survey of Methods Using Balanced Photodetection.
