Wavelength selectivity of in-line fiber-optic filter devices
Applied Optics, 1998We 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 ...

A generalized approach to optical low-coherence reflectometry including spectral filtering effects
Journal of Lightwave Technology, 1998 International audienceIn the interpretation of optical low-coherence reflectometry measurements, the reflectivity of the device under test is in general supposed to be with a slow dependency on optical wavelength.

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 ...

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 ...

Light filtering devices using background wavelength processing techniques
MRS Proceedings, 2012ABSTRACTThis 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, 2014Multiple-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 ...

A widely tunable dual-wavelength based on a microring resonator filter device
Laser Physics, 2018We 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

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 ...
