Abstract: Embodiments of the present disclosure provide example multi-core fiber interleavers, example optical fiber amplifiers, example transmission systems, and example transmission methods. One example multi-core fiber interleaver includes a first port, a second port, a third port, and a fourth port, respectively adapted to be coupled to a first multi-core fiber, a second multi-core fiber, a third multi-core fiber, and a fourth multi-core fiber. A first subset of a plurality of first cores is coupled to a first subset of a plurality of second cores. A first subset of a plurality of third cores is coupled to a first subset of a plurality of fourth cores. A second subset of the plurality of fourth cores is coupled to a second subset of the plurality of second cores. A second subset of the third cores is coupled to a second subset of the first cores.

Abstract: An optical signal transmitting device comprises an optical transmitter and a mode converter. The optical transmitter transmits a multi-path transmitted initial optical signal to the mode converter, wherein the initial optical signal comprises a first optical signal and a second optical signal both having a first wavelength, and a third optical signal having a second wavelength different from first wavelength. The mode converter is configured to perform phase conversion on the incident initial optical signal to obtain and reflect a first target optical signal, which is single-path transmitted and comprises the third optical signal, the first optical signal transmitted in a first mode, and the second optical signal transmitted in a second mode different from the first mode.
