| 摘 要： | 为满足高速高精光栅解调器的要求,研制了一种基于半导体光放大器(SOA)的高速扫频激光光源。采用傅里叶畴模式锁定(FDML)的工作模式和环形腔结构,能够提供调谐频率高于2000 Hz的窄带调谐光用于光栅解调,输出光功率大于12 dBm,大大提高了光栅解调的速度和信噪比。使用该光源的光栅解调器在扫描频率不低于2 000 Hz的条件下,精度能够达到2 pm。

| Abstract: | In order to satisfy the request of high-speed and high-precision grating demodulator,a high-speed frequency swept laser light source is designed based on semiconductor optical amplifier.This light source uses the work pattern of Fourier Domain Mode Locking and ring cavity geometry.It can provide narrow band tuning light for grating demodulation,and the tuned frequency is above 2 000 Hz.The output light power is higher than 12 dBm,and the source can greatly improve the speed and SNR of grating demodulator.Un... |
