A tunable optical device (100), comprising a receiver (40), a light-emitting module (10), an optical diaphragm (20) and a selective transmission module (30), wherein the light-emitting module (10) comprises a laser (12) and a refrigerating block (11), the laser (12) is installed on the refrigerating block (11), the refrigerating block (11) pre-sets a first working temperature and detects a working temperature of the laser (12), when the temperature detected by the refrigerating block (11) is higher than the first working temperature, the refrigerating block (11) starts and controls the working temperature to be maintained at the first working temperature, which causes the laser (12) to emit a first light beam with the wavelength thereof being a first working wavelength; an optical allocation network transmits a second light beam comprising at least one wavelength; the selective transmission module (30) comprises a first adjustable diaphragm (31) and at least one heating element (32), the optical diaphragm (20) reflects the second light beam onto the first adjustable diaphragm (31), the first adjustable diaphragm (31) selectively transmits the light with the wavelength matching the current temperature of the first adjustable diaphragm (31), and the heating element (32) pre-sets a second working temperature, so that the light of the second working wavelength, matching the second working temperature, of the second light beam passes through the first adjustable diaphragm (31) and is received by the receiver (40), and the above structure implements coaxial bi-directional receiving/transmitting adjustability. |
