High-gain balanced photodetector
Koheron PD10B is a balanced photodetector with 80 kV/A transimpedance gain and 8 MHz bandwidth. With a noise equivalent power of only 0.8 pW/√Hz at 1 MHz, the PD10B is a perfect alternative to the PD100B balanced photodetector for those who require a higher gain.

Characterization
Output power spectral density
The power spectral density of the PD10B photodetectors output was measured for different incident optical powers. The indicated power is the incident power per photodiode. Optical source is a Koheron LD101 laser at 1550 nm. Power spectrum is measured using the Koheron ALPHA250 FFT analyzer.
