摘要:
A tuneable optical filter (10, 110, 210, 310, 410) comprising an input waveguide (12, 412), an optical power coupler (14, 414), and two substantially parallel photonic crystal waveguides (16, 416; 18, 418) is disclosed. The optical power coupler (14, 414) is optically coupled between the input waveguide (12, 412) and the two parallel photonic crystal waveguides (16, 416; 18, 418), and the optical power coupler (14, 414) is adapted to split incoming light from the input waveguide (12, 412) into two in-phase light outputs, which are coupled to the two parallel photonic crystal waveguides (16, 416; 18, 418). The tuneable optical filter further comprises an actuator (36, 136, 236, 336, 436), which is arranged and adapted to be able to vary a spacing (d) between the two waveguides (16, 416; 18, 418).
摘要(中):
包括输入波导(12,412),光功率耦合器(14,414)和两个基本上平行的光子晶体波导的可调光滤波器(10,110,210,310,410) (16,416; 18,418)。 光功率耦合器(14,414)光耦合在输入波导(12,412)和两个平行光子晶体波导(16,416; 18,418)之间,并且适配光功率耦合器(14,414) 以将来自输入波导(12,412)的入射光分成耦合到两个平行光子晶体波导(16,416; 18,418)的两个同相光输出。 可调谐滤光器进一步包括致动器(36,136,236,336,436),该致动器被布置并且适于能够改变两个波导(16,416; 18,418)之间的间距(d)。 / p>
