Abstract: We present long-wavelength InGaAlAs-InP vertical-cavity surface-emitting lasers (VCSELs) with a buried tunnel junction (BTJ) and a well-defined polarization ...

Silver nanoparticles grown in nanochannels of anodic aluminum oxide on a grating form a surface-enhanced Raman scattering (SERS) substrate with the double resonance from both localized and delocalized ...

Anonymous The above sentence might get some quizzical looks from many of the folks who live in Eagle County. Why make it great again? Isn’t it already a ...

The emission spectra for control VCSELs with grating DCs of 0% and 100% are shown together with that for an HCG-VCSEL in Fig. 4. A DC of 0% corresponds to having no HCG layer, and a DC of 100% ...

Abstract: A new long-period fiber grating structure based on a tapered fiber side contacted with a metal grating is proposed and demonstrated in this paper. The temperature/index tuning sensitivity ...

Sound doesn't fossilise, of course. From what we know about animal behaviour, however, dinosaurs were almost certainly not silent. Now with the help of new, rare fossils and advanced analysis ...

Transport for London (TfL) could be bringing back the original Routemaster sound to indicate when a bus is about to depart. The old 'ding ding' sound is also being trialled with other sounds to ...
