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.

Abstract: A surface wave excitation device includes a transmission line disposed on a wire layer PCB, and a same quantity of layers are respectively disposed above and below the wire layer PCB. A copper wire is disposed on each layer of PCB, and the copper wire forms a closed region. Closed regions on the PCB that are respectively disposed above and below the wire layer PCB and that have a same distance from the wire layer PCB are in a same shape, and a closed region on a PCB farther away from the wire layer PCB occupies a larger area. The wire layer PCB includes first and second closed regions, the first closed region is disposed on one side of the transmission line, and the second closed region is disposed on the other side, and shapes of the first and second closed regions are mutually symmetrical with the transmission line as a symmetry axis.

Abstract: Embodiments provide an optical transceiver assembly for resolving a problem that an optical assembly has a large size. The optical transceiver assembly may include a first cavity, a second cavity and WDMs. The first cavity may include at least two optical receivers, which may be configured to receive light of different wavelengths, respectively. The second cavity may include at least two optical transmitters, may be configured to emit light of different wavelengths, respectively. Each of the at least two optical receivers and each of the at least two optical transmitters may correspond to different WDMs, respectively. The WDM corresponding to one of the at least wo optical receivers can be configured to: separate, from light emitted from an optical fiber, light of a wavelength receivable by the corresponding optical receiver, transmit the light to the corresponding optical receiver, and reflect the other wavelengths.

Abstract: The present invention discloses: when a first laser in N lasers is switched to a second idle laser in M lasers, a wavelength of a wavelength-selective optical element to which the first laser is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths. Similarly, when a first optical receiver in N optical receivers is switched to a second idle optical receiver in M optical receivers, a wavelength of a wavelength-selective optical element to which the first optical receiver is coupled is adjusted from a first wavelength to a second wavelength, and the second wavelength is different from the N wavelengths.
