Ultra-compact and low-loss polarization rotator based on plasmonic waveguide

A novel ultra-compact polarization rotator (PR) based on surface plasmon polaritons waveguide is proposed. The total footprint of the proposed device is only 0.44µm×2.55µm. Simulations with 3D-FDTD show that the PR has a broad bandwidth (1.4µm∼1.7µm) with extinction ratios larger…

A trick to improve PRD during compressed sensing ECG reconstruction

In the problem of compressed sensing (CS) successful reconstruction can be achieved by maintaining a low mutual coherence between the columns in the vector space. In this work, a way to increase the mutual incoherence is introduced. This is achieved…

Integrated microwave photonics phase shifter using on-chip stimulated Brillouin scattering

In this paper we consider two new topologies of a tunable microwave photonic phase shifter using stimulated Brillouin scattering. In the first topology, independent phase and amplitude control of an optical carrier was achieved by controlling two SBS pumps in…
