This paper presents a novel approach to generate a binary phase-coded microwave signal with accurate phase shift and large continuous operating bandwidth. In the system, the phase-coding modulation with an accurate phase shift has been realized by the joint use of two cascaded polarization modulators (PolMs). The generation of phase-coded microwave signals at 10 GHz, 18 GHz, and 28 GHz has...
A new and simple method based on the frequency-sweep method for measuring the frequency response of broadband optoelectronic devices is demonstrated. The electro-absorption modulator (EAM) can function as both modulator and receiver with the same frequency response. With this property, the frequency responses of a distributed feedback (DFB) laser at different bias currents were measured from dc to...
