Abstract
An optical receiver includes an avalanche photodiode (APD) having a light-receiving area provided on a face of a first substrate, the light-receiving area receiving a part of signal light; a photodetector having a light-receiving area provided on a face of a second substrate, the light-receiving area receiving the other part of the signal light; and a mounting member having a principal plane on which the APD and the photodetector are mounted. Due to this structure, crosstalk between the APD and the photodetector does not occur and an avalanche multiplication factor of the APD can be controlled on the basis of the output current of the photodetector.
Claims12
An optical receiver for receiving signal light, comprising:
- an avalanche photodiode including a first substrate and a light-receiving area provided on a face of the first substrate, the light-receiving area receiving a part of the signal light;
- a photodetector including a second substrate and a light-receiving area provided on a face of the second substrate, the light-receiving area receiving another part of the signal light;
- and
- a mounting member having a principal plane on which the avalanche photodiode and the photodetector are mounted,
- wherein the avalanche photodiode and the photodetector are arranged adjacent to each other on the mounting member such that a rear face of the first substrate and a rear face of the second substrate face the principal plane of the mounting member.
