OPTICAL FIBER COLLIMATOR, OPTICAL DEVICE, AND OPTICAL TRANSMITTER-RECEIVER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical fiber collimator having small PDL and light insertion loss by using a fiber collimator in which a nonaxisymmetric side pressure generated in a refractive index distribution fiber is suppressed, to provide an optical device and an optical transmitter-receiver. SOLUTION: The optical fiber collimator is characterized in providing: a base; an optical fiber; the refractive index distribution fiber connected to one end of the optical fiber, wherein both end parts of the refractive index distribution fiber come into contact with the upper face of the base via an adhesive, and the central part excluding both end parts is fixed separated from the upper face of the base.
