Disclosed are a single-optical-fiber bidirectional transceiving device and an optical fiber communication system. The device comprises a composite optical transmission port being coupled with an optical fiber; an optical input port for outputting an inputted emitting signal to the composite optical transmission port; an optical output port for outputting a receiving signal input from the composite optical transmission port; an bidirectional optical transmission assembly for transmitting the receiving signal input from the composite optical transmission port to an optical guide assembly and an emitting signal output from the optical guide assembly to the composite optical transmission port; and the optical guide assembly for transmitting the emitting signal input from the optical input port to the bidirectional optical transmission assembly and a receiving signal output from the bidirectional optical transmission assembly to the optical output port, whereby a bidirectional optical transceiving function can be realized through a single optical fiber.

A silicon waveguide coupling alignment apparatus includes a fine adjustment bracket, a stress releasing clamp and a silicon photonic integrated chip force sensor. A silicon photonic integrated chip is fixed on the silicon photonic integrated chip force sensor, at least a part of an optical fiber to be coupled is fixed on one end of the stress releasing clamp, the stress releasing clamp is arranged on the fine adjustment bracket, an end surface of the optical fiber to be coupled is aligned with an end surface of the silicon photonic integrated chip by adjusting a position of the fine adjustment bracket, and a cushioning mechanism is arranged within the stress releasing clamp to cushion a collision force in a direction perpendicular to the end surface of the optical fiber to be coupled. The contact force imposed by the optical fiber on the end surface of the chip can be released by the clamp.
