A Class-AB microwave-photonic link is presented as a means to reduce noise associated with DC-bias. By operating with two complementary, approximately half-wave-rectified, optical sources and generating the difference in a balanced detector, linear modulation with high modulation efficiency is achieved with near zero DC. Using two mode-converter intensity(More)
A novel microwave-photonic link is demonstrated using a unique AlGaAs-GaAs electrooptic mode-converter-based polarization modulator in a balanced output configuration. This enables suppression of common-mode intensity noise and optical-amplifier-induced beat noise using a polarization-selective balanced optical receiver. Unlike the conventional approach(More)
Cancellation of common-mode intensity noise in microwave-photonic links is found to be limited by the applied intensity modulation. A model is developed and verified experimentally for the dependence of the maximum noise suppression on modulation index, for two-tone and multichannel modulation. For example, for a root-mean-square modulation index of 0.3,(More)
The spur-free dynamic range (SFDR) of a novel microwave-photonic link, using a polarization mode-converter electro-optic modulator in a balanced output configuration, is characterized in this work. Common-mode intensity noise and optical-amplifier-induced beat noise are suppressed using a polarization-selective balanced optical receiver. In addition,(More)
