Abstract In this letter, by incorporating hybrid structure of no-core fiber (NCF)-graded index multimode fiber (GIMF) as the saturable absorber (SA) and spectral filter simultaneously, not only the switchable noise-like pulses (NLPs) but also the tunable single- and dual-wavelength dissipative solitons (DSs) are obtained from a net normal dispersion ...

Optical wavelength converter with a dynamic Brillouin filter and an electronic compensating device
Journal of the Optical Society of America B, 2006We present an experimental and theoretical study of a highly robust wavelength converter at 10Gbit/s that is based on a narrow bandstop Brillouin filter. The wavelength conversion takes place in a semiconductor optical amplifier in a cross-gain-phase process, which operates in a weak-modulation mode.

Development of wavelength selective shutters for device application for filters and smart windows
IEE Proceedings - Circuits, Devices and Systems, 1997Ideal wavelength selective shutters (or filters) need to have sharp, high intensity, easily switchable absorption bands in the desired region of the electromagnetic spectrum. If such devices are to be used for smart window applications, then selective control of all the visible and near infra-red regions of the electromagnetic spectrum would be ...

Wavelength filtering and demultiplexing devices based on ultrathin corrugated MIM waveguides
Journal of Modern Optics, 2015We have numerically investigated the transmission properties of spoof surface plasmon polaritons on the ultrathin corrugated metal–insulator–metal (MIM) waveguides with different grooves. A band-pass plasmonic filter with T-shaped grooves and a compact 4-way wavelength division demultiplexing (WDM) incorporating the filter have been proposed. The whole

Broadband Wavelength Filter Device using a Sidewall Grating in Multimode SOI Rib Waveguide
Optical Fiber Communication Conference, 2017A filter device with a flat-top passband of Δλ pb > 40 nm is demonstrated using multi-mode SOI waveguide with a side-wall grating. The passband is bounded by highly extinguished sidebands of Δλ sb > 10 nm.

Optical alignment is of importance in spectrum inspection which is inevitable in the manufacturing process for optical filters. In the past, mechanisms with several manual axes have been used to realize such alignment, but these axes are coupled to each other.

a b s t r a c t Three-dimensional numerical modeling of a controlled plasmonic filtering device based on Au nanorings in an SiO2 host has been investigated. It is shown that a certain plasmon waveguide based on an ordered array of Au nanorings which utilized as a waveguide ring resonator (WRR) can be used to control the propagated optical energy and ...

In this study, we investigated quantum dot intermixing (QDI) for InAs/InGaAlAs highly stacked QDs on an InP(311)B substrate with low-temperature annealing at 650 °C in order to realize integrated photonic devices with QDs and passive waveguides. In particular, we adopted the method of introducing point defects by ICP-RIE to realize a blue shift of the ...
