Low-noise APD Receivers

Photonics News 27

New Model


US27-952

The simplest way to use a detector is with a receiver circuit. Here the quality is judged according to the amount of noise produced. Our extremely low-noise silicon and InGaAs APDs offer the optimal prerequisites for detectors. For the entire system, however, the amplifier noise is the dominant source of noise.
To reduce the overall noise of the detector/amplifier module, the capacitance connected to the amplifier has to be as small as possible. This is achieved by making the connections as short as possible.


H0 series. Our team of developers put a lot of work into this. In our new H0 series of APD receivers, the name is our goal. The inherent noise of the receivers should be zero. Although this is physically not possible, our developers came very close to meeting this goal.


Depending on the integrated feedback resistor, a bandwidth from DC up to 80 MHz can be achieved. If the SAR500, our Si APD with a diameter of 500 µm, is integrated, the module has a noise equivalent power (NEP) of only 4.86 fW/√Hz at an amplification of 3 x 107 V/W. With the 80 µm or 200 µm InGaAs APD of the IAG series, the following values can be achieved:
1.1 x 106 V/W @ 0.47 pW/√Hz.
Due to the very compact, modified TO-5 housing with a diameter of approximately 5 mm, the H0 series APD receivers can be integrated into small systems with which, for example, distances can be measured or the smallest light signals detected.
