Abstract
The optical transmitter includes a FP-LD, generating multiple-longitudinal mode light wave. The FP-LD is also driven by an electrical signal, modulates the electrical signal to the multiple-longitudinal mode light wave, and outputts the modulated multiple-longitudinal mode light wave. An optical coupler, coupled with the FP-LD, is used for feeding the modulated multiple-longitudinal mode light wave from the FP-LD to a fiber Bragg grating. The fiber Bragg grating is for filtering the received multiple-longitudinal mode light wave according to a parameter, and feeding back the optical signal generated after being filtered to the optical coupler. The optical coupler divides the optical signal, thus making the optical signal oscillate between the FP-LD and the fiber Bragg grating to form a oscillation cavity, and outputs a single mode optical wave with constant wavelength and power.
