Among all scattering processes, spontaneous Brillouin scattering originates from the interaction between light and thermal acoustic waves propagating in the medium. The interference resulting from the incident light and its spontaneously backscattered frac ...
We have fabricated YBa/sub 2/Cu/sub 3/O/sub 7/ ramp-type junctions incorporating a barrier layer of NdGaO/sub 3/ with a nominal thickness of 2 nm. The junctions exhibit pronounced Josephson effects and operate up to 82 K. The characteristics are well descr ...

Two different types of micromirrors are integrated with a fiber laser to modulate the cavity Q-factor. Both systems operate at frequencies up to 60 kHz and generate a pulse peak power 100 times higher than the continuous emission. We simulate the emitted p ...
Two all-fiber wavelength tunable devices, one utilizing thermal tuning and a second based on strain tuning, have been produced by combining resistive Ti/Pt and piezoelectric ZnO fiber coatings with fiber Bragg gratings (FBGs). The Ti and Pt coatings with t ...
We have designed and fabricated three types of high- SQUID (superconducting quantum interference device) magnetometers based on step-edge Josephson junctions using three different concepts of coupling magnetic flux into the SQUID: (i) a single pickup loop ...
We report the first demonstration of an extremely simple and efficient 1.24 μm phosphosilicate fiber-based Raman laser with Bragg gratings written directly in the fiber used. The laser pumped by Nd fiber laser exhibits a slope efficiency of 80% ...
A tunable loss filter based on a long-period fiber grating and a Ti/Pt coating is presented Electrical wavelength tuning of 11 nm with an efficiency of 16.4 nm/W and modulation with 2 s rise time were achieved. ...
Brillouin-gain-spectrum measurement along an optical fiber has recently gained a lot of interest owing to its potential for strain monitoring in installed cables and for distributed temperature sensing. We present a method that has the following advantages ...
