摘要:

我们建立环形谐振器,以评估可果美空芯光子晶体光纤在未来应用于谐振旋转传感的潜力。可果美光纤的大模直径允许减小自由空间光纤到光纤的耦合损耗,导致对于等于15 cm的直径具有约30的精细度的腔。谐振线宽为3.2~MHz,对比度高达89%.与7-cell光子带隙(PBG)光纤的比较导致更好的精细度和对比度与Kagome光纤。基于这种光纤的谐振器与中到高性能旋转感测所需的角度随机游走兼容。与7-cell PBG光纤相比,在二氧化硅中传播的少量光还应允许在7-cell Kagome光纤中将克尔诱导的非互易性进一步降低至少三个数量级。

英文摘要:

We build ring resonators to assess the potentialities of Kagome Hollow-Core Photonic Crystal Fibers for future applications to resonant rotation sensing. The large mode diameter of Kagome fibers permits to reduce the free space fiber-to-fiber coupling losses, leading to cavities with finesses of about 30 for a diameter equal to 15 cm. Resonance linewidths of 3.2~MHz with contrasts as large as 89\% are obtained. Comparison with 7-cell photonic band gap (PBG) fiber leads to better finesse and contrast with Kagome fiber. Resonators based on such fibers are compatible with the angular random walk required for medium to high performance rotation sensing. The small amount of light propagating in silica should also permit to further reduce the Kerr-induced non-reciprocity by at least three orders of magnitudes in 7-cell Kagome fiber compared with 7-cell PBG fiber.
