The effects of a micrometer-scale silicon ring resonator with a FWHM of $0.078\mathrm{nm}$ $\left(9.6\mathrm{GHz}\right)$ on a nonreturn to zero amplitude-modulated optical signal with a modulation rate of $10\mathrm{Gbps}$ are experimentally investigated. By transmitting the optical signal through the device, significant spectral distortion and sideband attenuation is introduced, as characterized by amplitude Bode plots, and a power penalty of $0.8\mathrm{dB}$ is observed. Carrier wavelengths within the transmission resonance, but detuned from the center wavelength, are investigated as well. Numerical simulations further support the experimental results.
