Balanced Photodetectors
Femto Messtechnik GmbHRequest Info
The HBPR series of balanced photodetectors from FEMTO Messtechnik enable the differential measurement of optical signals with wavelengths from 320 to 1700 nm and bandwidths of up to 500 MHz.
By taking the exact difference between the two input signals, common-mode noise is suppressed, and the smallest optical signals can be extracted from the signal measurement path. The photoreceivers use two photodiodes selected in pairs, which are connected in an antiparallel and low-noise transimpedance amplifier to detect the differential signal. The optical inputs are optionally free space or fiber-coupled with low input noise down to 3.7 pW/√Hz and a high common mode rejection of up to 55 dB.
Various models with Si or InGaAs photodiodes and bandwidths from 100 to 500 MHz are available. Applications include optical spectroscopy, coherent heterodyne detection, homodyne detection of optical quantum states, optical coherence tomography, differential optical front end for oscilloscopes, spectrum analyzers, analog-to-digital converters, and lock-in amplifiers.
