Abstract

We demonstrate direct bandwidth measurement of multimode polymer waveguides based on an optical sampling technique. The pulse shape can be completely recovered after transmission due to the advantages of optical sampling technology in the field of ultrashort pulse measurement. A reduction in averaged bandwidth (Bandwidth-length products) from 241 GHz (27 GHz·m) to 180 GHz (20 GHz·m) of 11 cm-long straight waveguides is observed when using mode scramblers (MS) to fully stimulate the higher-order modes. The effects such as bending, crossing, and twisting of both the rigid and flexible waveguides on the bandwidth are also investigated. The proposed method is effective for measuring the bandwidth and dispersions of waveguides, fibers and optical devices with a short length for varies applications.
