Abstract: A variable optical attenuator with photoelectric detector, comprising a collimator, a variable optical attenuator chip, wherein the variable optical attenuator further comprises a photoelectric detector; and the photoelectric detector receives and detects partial light from the variable optical attenuator chip. The variable optical attenuator of the invention is capable of detecting attenuation change of itself via the variable optical attenuator chip. Thus, real-time monitoring and feedback are implemented, and the attenuation performance of the variable optical attenuator is improved.
