Abstract: The present application relates to an all-optical detector and detection system, a response time test system, and a manufacturing method. The all-optical detector comprises a micro-nanofiber and an optical resonant cavity. The micro-nanofiber comprises transition regions and a uniform region. The uniform region is connected to the transition regions. The optical resonant cavity is provided in the uniform region. The optical resonant cavity is made of a semiconductor material. The all-optical detector provided in the present application detects light by means of the change of a resonance peak, achieves all-optical detection, and has a high signal-to-noise ratio.
