PD10B - High-gain balanced photodetector
PD10B - High-gain balanced photodetector PD10B - Frequency response PD10B - Shot noise PD10B - Noise Equivalent Power

Koheron PD10B is a balanced photodetector with 80 kV/A transimpedance gain and 8 MHz bandwidth. With a noise-equivalent power spectral density 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-80-DC 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.
