Claim 12:
13. A non-transitory storage medium, upon which is stored with a computer program applied to an optical signal outputting device, wherein the computer program is executed by a processor to implement an optical signal outputting method applied to an optical signal outputting device which comprises a target optical fiber grating, the method comprising:
emitting, by a pump laser, a first optical signal whose central wavelength is a target wavelength of a target band optical signal when a target band optical signal emitting command is received;
screening a second band optical signal and the target band optical signal from the first optical signal and return a part of the target band optical signal and/or the second preset band optical signal to the pump laser by using the target optical fiber grating; and
triggering a resonance operation by using the second band optical signal or the target band optical signal to convert the second band optical signal into the target band optical signal by using the resonance operation, and outputting the target band optical signal.
