文摘

A silica based quasi-periodic clad leakage channel fiber (LCF) is proposed. The single mode operation is ensured by means of high order mode filtering. The proposed LCF exhibits a large loss ratio (>103)(>103) between LP11LP11 and LP01LP01 modes. The large loss ratio is achieved by leaky modes and resonant modes coupling. Reported a low bending loss of 0.04 dB/m for LP01LP01 mode.
