摘要： An embodiment of the inventive concept includes an optical signal generating circuit, a controlling circuit, a waveform shaping circuit, and an output circuit. The optical signal generating circuit generates a first optical signal including pulses. The controlling circuit generates a control signal indicating a first pulse to be attenuated in magnitude among the pulses. The waveform shaping circuit attenuates a magnitude of the first pulse based on the control signal and the first optical signal, and generates a second optical signal including pulses corresponding to the pulses included in the first optical signal and the first pulse having the attenuated magnitude. The output circuit outputs an electric signal of bands corresponding to differences between frequencies of the pulses included in the second optical signal based on the second optical signal. A band corresponding to the first pulse among the bands of the electric signal is adjusted as the magnitude of the first pulse is attenuated.

摘要： Disclosed are an avalanche photodiode with a guard ring structure that relieves edge breakdown by an external voltage which is applied through a metal pad which is attached to the guard ring and a manufacturing method thereof. An avalanche photodiode with a guard ring structure includes a plurality of semiconductor layers laminated on a substrate; an active region partially formed above the semiconductor layers; a guard ring which is formed above the semiconductor layers and disposed so as to be spaced apart from the active region and have a ring shape that encloses the active region; and a connecting unit formed on the semiconductor layers to be electrically connected to the guard ring so as to apply an external voltage to the guard ring region. Therefore, the external voltage is applied to the guard ring of the avalanche diode through the connecting unit to relieve the edge breakdown.
