Abstract

We have investigated the general characteristics of the power penalty due to the fiber chromatic dispersion effects in both fiber-wireless and photonic time-stretching systems. Two different modulation schemes have been demonstrated to reduce this penalty using our novel polymer modulators incorporating a multimode interference (MMI) structure. A single-sideband (SSB) modulator configuration has almost completely eliminated this penalty without a bandwidth limit. A double-sideband (DSB) modulator configuration with an appropriate quadrature bias has also shown significant improvement in bandwidth limitations for a given fiber link length.
