The monolithically integrated all-optical single-sideband (SSB) filter based on photonic Hilbert transform and planar Bragg gratings is proposed and experimentally demonstrated. An SSB suppression of 12 dB at 6 GHz and sideband switching are achieved via thermal tuning. An X-coupler, photonic Hilbert transformer, flat top reflector, and a micro heater are incorporated in a single silicon-on-sil...

require high-fi nesse, high-quality factor (highQ ) micro-lasers. Such lasers must be exceptionally transparent at their emission wavelength. But if highQ micro lasers exhibit correspondingly weak absorption at the pump wavelengths, they are challenging to excite. Here, we demonstrate micro-ring lasers that exhibit Q > 5.2 × 10 6 and a fi nesse of > 1.8 × 10 4 with a direct-illumination, non-re...

We report results of nitrogen and argon adsorption experiments performed at 77.4 and 87.3 K on novel micro/mesoporous silica materials with morphologically different networks of mesopores embedded into microporous matrixes: SE3030 silica with worm-like cylindrical channels of mode diameter of approximately 95 angstroms, KLE silica with cage-like spheroidal pores of ca. 140 angstroms, KLE/IL sil...

Micro-silica is a highly efficient mineral additive whose role reflected in improvements of microstructure packing, strength and durability non-shaped composite building materials such as concrete mortar. A comparative study performances rendering mortars with different quantities micro silica was conducted. The experimental program included production reference mortar based on Portland cement ...

The ability to predict the micro-scale strength and plasticity of fused-silica micro-components is crucial as their miniaturization applications in harsh environments advance. This study focusses on micro-mechanical behavior fused silica micropillars at high temperatures variable strain rates. 160 with a diameter 1.6 µm have been tested between ?120 °C 600 rates 10-3 s?1 1 s?1, which are date u...
