A Practical Method for Coupling Between Semiconductor Laser and Graded-core Fiber
Author(s): 
Pages: 424-426
Year: Issue:  6
Journal: LASER & INFRARED

Keyword:  半导体激光器球彩透镜耦合效率变芯径光纤;
Abstract: 文中提出了一种新的实用化光纤耦合方案,将大芯径石英光纤的一端熔成球形(用于与半导体激光器的耦合),另一端拉制成变芯径光纤,这样有利于与其它光学系统的连接.结果表明:采用该方法耦合效率达到75%左右,同时大大地增加了耦合系统的失调容差,降低了调试和封装的难度,因而有着广泛的实际应用价值.
