Abstract :
Summary form only given. In this paper, we report the LP/sub 02/ mode dispersion-compensating scheme based on a hollow optical fiber mode converter (HOF-MC) in a ring-core index dispersion compensating fiber (DCF) in order to couple to the LP/sub 02/ mode more efficiently. Since the MC is based on an adiabatic transformation of the guided mode without a periodic structure, it is inherently robust against environmental influences and could be spliced to conventional single-mode fibers (SMFs) with low loss. Design parameters of both the ring core DCF and the mating MC are discussed to optimize average compensated dispersion and dispersion slope in the conventional band (C-band, 1.53-1.57 /spl mu/m) of erbium-doped-fiber amplifiers (EDFAs), and the differential modal delay between LP/sub 01/ and LP/sub 02/ modes is also analyzed.
