Abstract
We propose a new scheme to generate broadband linearized optical single-sideband (OSSB) signal for radio over fiber systems. By using an unbalanced dual parallel Mach-zehnder modulator (DPMZM) followed by optical filtering, a linearized OSSB signal is obtained. With coherent detection, radio frequency (RF) signal can be recovered with simultaneously suppressed second-order distortion and third-order intermodulation. This scheme can be used to realize broadband systems with wide dynamic range.
