A novel broadband and scalable RF switch matrix based on microwave photonics is proposed and the proof-of-concept experiments are carried out. The experiment results show that the proposed RF switch matrix is with a good linearity, link gain, port isolation and EVM performance.
In this article, we propose and demonstrate a new approach to implement microwave photonic filter with tunable and switchable dual-passband based on a reflective fiber Mach-Zehnder interferometer and dispersive medium. The proposed MPF has simple structure and is easy to implement, also the experimental results show good tunability and switch performances.
We use intensity and phase modulators to develop a 10-GHz optical frequency comb whose shape can be easily switched between extremely flat-topped (38-lines within 1-dB) and Gaussian (36-lines over 15-dB dynamic range).
We use the m-line spectroscopy technique to characterize the guiding modes in alkoxysilane dye (ASD) doped polymethyl methacrylate film waveguide. All-optical switching phenomenon with response time of ps was observed with improved prism-waveguide coupling.
