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.
