Cascade synthesis approach in transformed frequency domain (z-domain) is reformulated to cover the extraction of complex (s = sigma +j omega) and sigma -axis transmission zeros (TZs) in addition to the usual j omega -axis TZs. It is shown that complex conjugate quadruplets of TZs (s = +/- sigma +/- j omega) can be extracted as fourth order sections by applying zero shifting technique to the TZs at both s=0 and s=infinity. The resulting fourth order sections are then transformed into cross-coupled forms with four coupled resonators, termed as linear phase Cascade Quadruplet (CQ) block. Such CQ blocks can be cascaded with the j omega -axis finite Triplet) blocks to realize linear phase filters with symmetric or asymmetric amplitude response.

Quantitative analysis of nonlinear dynamics of quantum light transmission in strongly coupled quantum dot-cavity systems
Tugen, Alperen; Kocaman, Serdar (Elsevier BV, 2019-04-01)
We compared transmission spectra of coupled high-Q cavity with quantum dot (QD) systems in the strong coupling regime with Input-Output Formalism (IOF) and Incoherent Pumping Mechanism (IPM) based on Lindblad master equation approach. The peak transmission of Dipole Induced Transparency (DIT) together with its full-width-half-maximum (FWHM) are enquired for detailed analysis. Both methods exhibit the same vacuum Rabi splitting in on-resonant case, in contrast, the peak of DIT is estimated smaller between 50...

Incorporation of hydrophilic multifunctional compounds in to the polymeric membrane's matrix is one of the useful methods for modification of mixed matrix membranes. Therefore, in this study, preparation and properties of polyethersulfone (PES) mixed matrix membranes with hydrolyzed polymethylmethacrylate (PMMA(hyd)) grafted on graphene oxide (GO-PMMA(hyd)) is investigated as an effective additive to improve permeability and antifouling properties. In this respect, grafting of PMMA(hyd) on the GO surface is...
