Wavelength selectivity of in-line fiber-optic filter devices

Applied Optics, 1998
We present an analysis of the performance characteristics of in-line fiber-optic bandpass and band-stop wavelength filters. A planar waveguide model was used for numerical simulations of the device performance. It was recently reported that the band-stop and the bandpass characteristics of a filter device depend on the depth of polishing of a single ...

Light filtering devices using background wavelength processing techniques

MRS Proceedings, 2012
ABSTRACTThis paper reports on light filtering devices based on a-SiC:H tandem pi´n/pin heterostructures. The spectral sensitivity is analyzed. Steady state optical bias with different wavelengths, are applied from each front and back sides and the photocurrent is measured. Results show that it is possible to control the sensitivity of the device and to

Multi-wavelength filters in silicon using superposition sidewall Bragg grating devices

Optics Letters, 2014
Multiple-filter stopbands, with the potential to be nonuniformly spaced in frequency, are realized in a single integrated Bragg grating device on silicon. By utilizing a superposition of sidewall relief grating functions, N individual filter responses can be fabricated with a device length N× shorter than the equivalent serial set of gratings ...

NCF–GIMF device as SA and filter utilized in tunable single- and dual-wavelength Yb-doped mode-locked fiber laser

Optics Communications, 2021
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 ...

Wavelength filtering and demultiplexing devices based on ultrathin corrugated MIM waveguides

Journal of Modern Optics, 2015
We 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

A multipurpose WDM holographic device for filtering, wavelength multiplexing and routing applications

Photonic Network Communications, 2006
This work describes the theory, design, and experimental results of a generic multipurpose device that can operate as a tunable wavelength filter, wavelength multiplexer and wavelength router. This device could be especially useful in optical networks applications based in both Coarse and Dense Wavelength Division Multiplexing technology (CWDM/DWDM ...

A widely tunable dual-wavelength based on a microring resonator filter device

Laser Physics, 2018
We demonstrate a stable, tunable dual-wavelength (DW) generated by launching an in-house built supercontinuum (SC) into an add-drop microring resonator (MRR). The MRR is fabricated from a silicon–nitrogen–oxygen substrate. The frequency comb of the filtered SC is obtained with an experimental free spectral range (FSR) from 0.39 to 0.46 nm corresponding
