Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant ...

When the electro-optic and acousto-optic effects are combined into a single device, the resulting acousto-electro-optic (AEO) modulator shows improved flexibility to overcome some limitations of the individual modulators ...

A silicon Mach-Zehnder interferometer is designed, fabricated and experimentally demonstrated for the C-band. Several interferometers were designed with different free spectral ranges. The influence of the waveguide width ...

Measurements on a passive optical fibre tunable filter are presented. The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a coupler. The novel ...

A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...

Photonic filters can be used for filtering the espectrum of wide-band optical sourcers such a ligth emmitting diodes (LED) or multimode laser diodes (MMLD). In this work the use of birefringent optical media such a ...
