Abstract
We present a novel and accurate method for characterizing the reflection spectra of distributed Bragg reflectors using optical frequency domain reflectometry. A compact test structure with integrated reference mirror and photodetector is designed, which overcomes the dependence on the fiber-to-waveguide coupling.
