The reflection and transmission of plane electromagnetic waves on monolayer graphene are studied theoretically in this paper. From an point view, is described as “infinitely thin” sheet characterized by a surface conductivity, based microscopic quantum dynamical approach, the becomes anisotropic presence both electrostatic magnetic bias. In work, starting from boundary conditions phase-matching...

An all-fiber wavelength-tunable narrow-linewidth polarization-maintaining (PM) Tm-doped fiber master oscillator power amplifier (MOPA) system is presented. We demonstrate an ring cavity master-oscillator (MO) with a tuning range of 110 nm (from 1925 to 2034 nm). The maximum output 459 mW obtained at 1992.9 for 16 W launched pump 793 nm, corresponding slope efficiency 5.6% concerning power. By u...

Abstract The study on the excitations of whispering gallery mode (WGM) resonances optical bottle microresonator (BMR) partially coated with a thin gold Au metal film is presented. BMR was fabricated through “soften-and-compress” technique small section standard fibre. Depositing particles spheroidal curvature surface yields metal-film meniscus profile 200 nm maximum thickness and tapered edges....

We experimentally demonstrate a stretchable plasmonic structure composed of a monolayer array of gold semishells with dielectric cores on an elastic PDMS substrate. The composite structure is fabricated using simple and inexpensive self-assembly and transfer-printing techniques, and it supports Bragg-type surface plasmon resonances whose frequencies are sensitive to the arrangement of the metal...

We present a photonic-plasmonic mode converter using modecoupling-based polarization rotation for connecting a silicon wire and hybrid plasmonic waveguides on a metal-inserted silicon platform. By using the polarization rotator based on defect-introduced silicon wire waveguide, the proposed mode converter can convert the photonic TE mode into the hybrid plasmonic TM mode. At the beginning, to i...

A polarization-independent reflective grating with improved bandwidth is presented based on the mixed metal-dielectric grating. The novel grating is composed of the substrate, the metal slab, two dielectric layers, and the covering layer. The grating parameters are optimized for the special duty cycle of 0.6 at an incident wavelength of 1550 nm used in dense wavelength division multiplexing (DW...

An efficient polarization beam splitter (PBS) based on an optofluidic ring resonator (OFRR) is proposed and experimentally demonstrated. The PBS relies on the large effective refractive index difference between transverse-electric (TE) and transverse-magnetic (TM) polarization states, since the silica-microcapillary-based OFRR possesses a slab-like geometry configuration in the cross section th...

We report the generation of harmonic noise-like mode-locked pulses in a thulium-doped fiber laser. In this laser, mode-locking can be realized through nonlinear polarization rotation (NPR) technique. The ring cavity configuration uses 5 m Tm-doped dual-cladding fiber, as gain medium, pumped by 793 nm diode couple controllers (PCs) and polarization-dependent isolator to form polarization-rotatin...

Vesicles composed of an anionic and a cationic surfactant, with a net negative charge, associate strongly with a hydrophobically modified polycation (LM200) and with an unmodified polycation with higher charge density (JR400), forming viscoelastic gel-like structures. Calorimetric results show that in these gels, LM200 induces a rise of the chain melting temperature (Tm) of the vesicles, wherea...
