Abstract
Fiber grating lasers have been theoretically investigated. Stabilizing the conditions ac米兰中国官网 the lasing wavelength ac米兰中国官网 fiber grating lasers against temperature change is discussed on the basis ac米兰中国官网 mode-hopping control. It is shown that, to reduce irregular and large-jump mode hopping, which originate in the longitudinal modes ac米兰中国官网 the semiconductor optical amplifier chip, the front facet reflectivity ac米兰中国官网 the chip should be less than 0.05 %. Two approaches to controlling mode hopping are proposed: extending the temperature period and reducing the wavelength change ac米兰中国官网 hopping.
