摘要:
选择不同的光学衬底,采用纳米光纤锥直接耦合的方法,测量微光纤传输损耗与光学衬底之间的关系,分析损耗机制,探索降低损耗的有效方法.结果表明:放置于MgF2及CaF2光学衬底上的微光纤传输损耗明显高于悬置于空气中的损耗值;衬底的折射率越接近光纤的折射率,置于其上的微光纤传输损耗越大;在同一种光学衬底上,微光纤直径越大,其传输损耗越小;光学衬底的存在,使微光纤中光场能量中心向衬底方向偏移,增加了传输损耗;采用将微光纤部分悬空的方法可有效降低传输损耗.
Abstract:
By depositing on different substrates, the relationship between the propagation loss of microfiber and the substrate is measured through direct coupling of microfiber and tapered nanofiber. The loss mechanics is analyzed and the effective methods to reduce the propagation loss is also proposed. It demonstrates that the losses of microfiber deposited on the MgF2 and CaF2 substrates are much higher than the one of the air-suspended microfiber. When the optical index of the substrate closes to the microfiber index, the propagation loss of the microfiber deposited on the substrate increases. On the same substrate, the propagation loss decreases with the increase of the microfiber diameter. The existence of the substrate drags the center of the optical energy field to the substrate and leads to higher loss. By suspending a part of the microfiber in air, the propagation loss can be effectively reduced.
