摘要： A tunable laser includes a housing having a sealable accommodating cavity, an optical interface and an electrical interface disposed on the housing, a tunable semiconductor laser apparatus, a splitter component, and a photodetector. The tunable semiconductor laser apparatus is disposed in the accommodating cavity for emitting an optical signal whose wavelength is tunable. An electrical signal inputted through the electrical interface controls the tunable semiconductor laser apparatus to emit the optical signal. The optical signal is outputted through the optical interface. The splitter component and the photodetector are disposed outside the housing. The optical signal is split into at least two beams of light by the splitter component after the optical signal is outputted through the optical interface. The photodetector is configured to receive one of the beams of light to monitor the optical signal emitted by the tunable semiconductor laser apparatus.
