| titleOfInvention | Chirp compensation method and driver for an optical modulator |
| abstract | Embodiments of the present application disclose a chirp compensation method and a driver for an optical modulator, which relate to the technical field of optical communication. The chirp compensation method for an optical modulator is applied to a driver, the driver includes an adjustable resistor RP1, and the chirp compensation method is applied to a driver. The compensation method includes the following steps: adjusting and outputting a differential signal VRFup and a differential signal VRFdw with different amplitudes based on the resistance value of the adjustable resistor RP1, so that the optical modulator is regarded as equal based on the output differential signal VRFup and differential signal VRFdw optical phase and light phase In the embodiment of the present application, the phase angle of the MZI modulator when modulating "1" and "0" is exactly 180°, which realizes chirp compensation of the optical modulator, reduces the influence of chirp, and avoids material process defects. The high chirp leads to damage to the transmission performance of the optical module, reduces the chirp index requirements of the optical modulator, improves the limit optical signal-to-noise ratio tolerance, increases the transmission distance, shortens the production time, and improves the production efficiency and device Yield. |
