1. An optical signal outputting device comprising:
a target optical fiber grating having a preset angle optical fiber grating and/or a preset period optical fiber grating;
a first optical fiber grating connected to the target optical fiber grating; and
a pump laser connected to the first optical fiber grating;
wherein the pump laser is configured to transmit a first optical signal to the first optical fiber grating when a target band optical signal emitting command is received, a central wavelength of the first optical signal being a target wavelength of a target band optical signal; and to convert a second band optical signal into the target band optical signal by using resonance and output the target band optical signal when an optical signal adjusting command is received;
wherein the first optical fiber grating is configured to screen a first band optical signal from the first optical signal and transmit the first band optical signal to the target optical fiber grating, a central wavelength of the first band optical signal being the target wavelength of the target band optical signal and a band scope of the first band optical signal being smaller than a band scope of the first optical signal; and
wherein the target optical fiber grating is configured to screen the second band optical signal and the target band optical signal from the first band optical signal, and return, by the preset angle optical fiber grating and/or the preset period optical fiber grating, a part of the target band optical signal and/or the second preset band optical signal to the pump laser, to transmit the optical signal adjusting command to the pump laser by using the second band optical signal or the target band optical signal.
