Paper Abstract

We present a method which applies a combination of the phase modulator, butt-couple and prism coupler to the measurement of individual mode's bending loss in multimode waveguides. By tuning the effective length of a channel waveguide with a phase modulator, the contrast in the transmitted intensity of Fabry-Perot resonance for individual guided mode separated by a prism coupler can be measured. The associated bending loss is obtained from these experimental results.
