Koheron PD100 photodetectors are amplified photodetectors with a bandwidth in excess of 100 MHz. Designed for shot noise limited operation with hundreds of µW of incident power, PD100 photodetectors make perfect candidates for coherent sensing. PD100 photodetectors are available with mounted InGaAs photodiode or without photodiode and in AC or DC coupled versions.
