Abstract

一种可调谐激光器(300、1100)，包括增益模块(301、1101)、正弦梳状滤波器(302、1103)、窄带梳状滤波器(303、1102)、波长配置电路(304、1105)和波长调谐电路(305、1104)。正弦梳状滤波器(302、1103)具有相互间隔的带通滤波窗口，窄带梳状滤波器(303、1102)具有相互间隔的带通滤波窗口。波长配置电路(304、1105)用于接收波长信息，根据波长信息设置第一波段的位置，波长调谐电路(305、1104)用于调谐窄带梳状滤波器(303、1102)的带通滤波窗口，使第一波段和第二波段重叠。可调谐激光器(300、1100)能够快速调谐激光。
