Laser Linewidth Measurements Using Self-Heterodyne Detection With Total-Reflected Delay Line

摘要：

　　As an important parameter in the laser communication system,the narrow linewidth of tunable laser source (TLS) must be measured accurately.Therefore,the linewidth of a TLS was measured with the delayed self-heterodyne detection method in the present work.The total-reflected delay line was used in the measurement system for make full use of 25km single-mode fiber delay line.The measured linewidth of the 1550 TLS is of 127 kHz,in agreement with the nominal value.
