Abstract

A compact (plug = 1.5 g) low-loss lens connector for single-mode fibers (SMF) which can operate in a wide range of wavelengths was developed. This lens connector consists of two lens assemblies using 250-microm diam AR coated sapphire balls precisely positioned between the SMF endfaces. The lens connection loss between the same kind of SMFs with a Gaussian beam spot radius ranging from 3.55 to 6.63 microm is predicted to be < or =1.0 dB. The average lens connection loss is 0.54 dB. Loss reproducibility after connecting 1000 times is less than or equal to +/-0.15 dB.

摘要

开发了一种紧凑的（插头 = 1.5 g）低损耗单模光纤（SMF）透镜连接器，其可在很宽的波长范围内工作。该透镜连接器由两个透镜组件组成，使用直径为250微米的增透膜蓝宝石球精确地定位在单模光纤端面之间。对于高斯光束光斑半径在3.55至6.63微米之间的同类单模光纤，预测透镜连接损耗小于或等于1.0 dB。平均透镜连接损耗为0.54 dB。连接1000次后的损耗重复性小于或等于±0.15 dB。
