A simultaneous all-optical upconversion technique for cost-effective wavelength-division-multiplexing (WDM) radio-over-fiber (RoF) applications utilizing a semiconductor optical amplifier (SOA) Mach-Zehnder interferometer is investigated. The proposed upconversion scheme uses only one frequency upconverter for multi-RoF channels, thereby reducing the(More)
All-optical signal up-conversion into the millimeter-wave frequency band is demonstrated using a semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) wavelength converter, which is based on a cross phase modulation (XPM) effect in the SOA. This scheme shows good conversion efficiency with polarization immunity and no increase in phase(More)
An electrooptic near-field mapping system based on a gain-switched distributed-feedback pulsed laser and a CdTe electrooptic crystal was used for characterizing transient and stationary near-field patterns of conventional and uniplanar compact photonic bandgap (UC-PBG) finite-width conductor-backed coplanar waveguides (FW-CBCPWs). Comparison of transient(More)
