Using parametric amplification in a highly nonlinear fibre, we demonstrate a widely tunable modelocked multiwavelength ring laser generating up to six simultaneous modes with 4.4 ps pulse width at
We fabricate tunable semiconductor lasers with two coupled photonic crystal cavities that allow up to 46 nm tuning range with a side-mode suppression ratio greater than 30 db.
We demonstrate tunable semiconductor lasers based on three coupled photonic crystal cavities, that allows up to 18 nm tuning range with a side-mode suppression ratio greater than 3.5 dB, in two dif
A hybrid III-V on silicon laser, integrating two intra-cavity ring resonators, is fabricated by using a wafer bonding technique.
Locating services in public environments substantially differs from finding services in a private local network (e.g. a home network).
We measure a resonance in the frequency dependence of the real diagonal conductivity, Re{[}sigma(xx)], near integer filling factor, nu = 3.
When a strong magnetic field is applied perpendicularly (along z) to a sheet confining electrons to two dimensions (x-y), highly correlated states emerge as a result of the interplay between electr
The crystallographic (charge-ordered) and magnetic superstructures of La0.333Ca0.667MnO3 were studied by high-resolution synchrotron x-ray and neutron powder diffraction.
We review recent progress on high bit rate long-haul optical transport systems, with spectral efficiency times transmission distance as the main figure-of-merit.
Standard cells are now a mainstay of the ASIC industry.
