阅读说明：本技术 一种可调谐激光器 (Tunable laser ) 是由 罗俊 冯志勇 于 2017-05-04 设计创作，主要内容包括：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。(A tunable laser (300, 1100) comprises a gain module (301, 1101), a sinusoidal comb filter (302, 1103), a narrow band comb filter (303, 1102), a wavelength configuration circuit (304, 1105) and a wavelength tuning circuit (305, 1104). The sinusoidal comb filters (302, 1103) have mutually spaced bandpass filter windows and the narrowband comb filters (303, 1102) have mutually spaced bandpass filter windows. The wavelength configuration circuit (304, 1105) is configured to receive wavelength information, set a position of the first band based on the wavelength information, and the wavelength tuning circuit (305, 1104) is configured to tune a bandpass filter window of the narrowband comb filter (303, 1102) such that the first band overlaps the second band. The tunable laser (300, 1100) is capable of rapidly tuning the laser.)
