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.

Located at the meeting point between telecom operators and over-the-top service providers, metro networks are particularly well suited for the introduction of radical acceleration of dynamics in th

This study investigated the effect of moving from small offices to a landscape environment for 19 Visual Display Unit (VDU) operators at Alcatel Denmark AS.
