Abstract
A feedback light tuning device and the optical communication system and method using the same are provided. By tuning the feedback light, the mechanism can completely correct the mean-wavelength drift up to 30 nm or 19400 ppm. The mechanism can be applied to various harsh environments which cause the mean-wavelength drift, so as to achieve a required stable mean-wavelength for the light source and to increase the acceptable range of radiation dose.
