Arrangement for regulating the output power of a semiconductor laser for a data transmission system including a light conductive fiber through which the laser power is transmitted and a photodiode which is responsive to light energy produced by the laser and whose output signal is utilized, possibly after appropriate amplification, to regulate the laser current. The photodiode is a thin-film photodiode which is transparent for the light frequencies to be transmitted via the light conductive fiber and is inserted in the light-conductive fiber used to transmit the signals. |
