对于具有信息容量大及单模干涉优点的单模光纤通讯和各种光纤传感器来说,都必须采用高效率的耦合器,为了降低连接损耗,提高耦合功率,Sheem和Giallorenzi共同研究出一种腐蚀——研磨技术,采用这项技术可以保证耦合器中的两块石英块(包括光纤芯)之间的严密接触,用这种方法制造的光纤耦合器具有连续可调、传输损耗低,不受偏振影响及高导向性等优点。可作为串联系统中可调的发送/接收耦合器及并联系统中的功率分束器及光纤
For single-mode optical fiber communication and various optical fiber sensors with the advantages of large information capacity and single-mode interference, an efficient coupler must be used. In order to reduce the connection loss and increase the coupling power, Sheem and Giallorenzi jointly developed a kind of corrosion - Grinding technology, using this technology can ensure that the two quartz blocks in the coupler (including the optical fiber core) in close contact between the fiber coupler manufactured by this method has a continuous adjustable low transmission loss, not Polarization effects and high guidance and so on. Can be used as a series system adjustable transmit / receive coupler and parallel system power splitter and optical fiber
