Abstract

We measured linear and quadratic dispersion on millimeter-length fibers, waveguides, and nanowires based on common-path spectral interferometry. We obtained the linear dispersion parameter, ${\beta }^{\prime }$, with a relative precision of $1.45\times {10}^{-4}$, and extracted the quadratic dispersion parameter, ${\beta }^{″}$, from the Taylor expansion of ${\beta }^{\prime }$. ${\beta }^{″}$ values show a discrepancy of $<1\%$ when compared with simulation as well as with measurement results obtained by a conventional Michelson interferometer. Using this method, we experimentally confirmed the sign inversion of the group velocity dispersion of $\mathrm{AlGaAs}$ nanowires for what is believed to be the first time.
