Paper Abstract

The radial gradient-index(RGI) glass rod lens system has been studied for semiconductor laser diode (LD) to single mode fiber (SMF) optical power coupling. Already a high performance piano-convex singlet lens system was developed and reported.(1) This time, a new RGI doublet lens system composed of a plano-convex lens and a plano-plano lens has been developed. This new system has wide alignment tolerances compared with the singlet lens system. This new system has about 2dB loss reduction, compared with a conventional one under mass production (at wavelengths of λ = 1.3µm, 1.55µm.
