A novel twin-core fiber connector

摘要

A novel twin-core fiber connector has been made by using two pieces of gradient refractive index (GRIN) lenses. The coupling loss of this connector is analyzed and several impact factors, such as lens length, focusing length of the specific matching conditions are discussed. Those factors that cause more transverse displacement have much greater coupling loss sensitivity, and the system tolerance is also considered to evaluate the practicability and the fabrication technologies.
