Abstract
In a detector for detecting a frequency-modulated light wave including a PIN photodiode (2), biasing means (11, 12, 15) are introduced which are capable of automatically forward biasing or reverse biasing the PIN photodiode (2) depending on the received light power. The output voltage of a transimpedance preamplifier stage (6) receiving the signal from the PIN photodiode (2) is thus automatically limited to a value below the saturation threshold of this transimpedance preamplifier stage (6).
