We report on the formation of a complete band gap for spin waves in a two-dimensional magnonic crystal consisting of a periodic hole lattice. We go beyond the partial band gaps observed so far in that we apply a magnetic field perpendicular to the permallo ...
Frequency stabilization of a diode laser locked to a whispering gallery mode (WGM) reference resonator made of a MgF2 single crystal is demonstrated. The strong thermal dependence of the difference frequency between two orthogonally polarized TE an TM mode ...
Recently stacked metamaterial structures coupled to a conductive plane have been investigated and have been shown to exhibit the same properties as stacked structures with double the layers, due to dipole mirror coupling. Here we study a system of stacked ...
Bragg gratings were inscribed in H2-loaded SMF-28e optical fibers and measured for axial stress changes for various exposure doses. Mean refractive index changes as high as 7.5 × 10-3 were observed under cw-244 nm irradiation of 143 W/cm2. Bragg grating re ...
An ArF excimer laser was used to fabricate Bragg gratings in fibers with Bi-SiO2 core and microstructured or F-doped claddings without fiber presensitization. Average and modulated refractive index changes of 2.7 x 10(-4) and 1.0 x 10(-4) were induced in p ...
A cw-244-nm-Ar+ laser was used to fabricate Bragg gratings in pristine and H-2-loaded Bi-Al-SiO2 optical fibers with index changes as high as 3.6 x 10(-4) and 19.3 x 10(-4), respectively. For comparison, fiber Bragg gratings in pristine and H-2-loaded SMF- ...
An imaging based interferometric pressure sensor apparatus compromise a fluid pressure sensor unit (1) and an optical monitor (2). The disposable pressure sensor part comprises a rigid transparent cover plate 3 and a flexible diaphragm (4), in between form ...
We report a study of the quantum dot (QD) emission in short photonic crystal waveguides. We observe that the quantum dot photoluminescence intensity and decay rate are strongly enhanced when the emission energy is in resonance with Fabry-Perot (FP) cavity ...
The energy transfer between the two interacting optical waves in a distributed sensor based on stimulated Brillouin scattering can lead to a non-uniform spectral distribution of the pumping power after a long propagation. This results in a spectrally disto ...
