TL;DR: In this article, the electrical surface properties of ultrananocrystalline diamond/amorphous carbon composite films have been investigated by four-point probe I/V and Hall measurements, whereas impedance spectroscopy has been used to establish the electrical bulk properties of the films.

TL;DR: In this article, a ridge waveguide laser was coupled with two micro-ring resonators with diameters between 20-60 /spl µ/m and 45/spl deg/ facets, achieving a free spectral range of about 18 nm.

TL;DR: Two 10 Gbit/s signals are individually wavelength converted via four wave mixing with no cross talk in a broad band 1550 nm quantum dash optical amplifier.

TL;DR: Recently developed, highly effective technologies enabling slow light propagation as a tunable feature in photonic devices, are reviewed in this paper, where several applications in ICT are also demonstrated, such as controlling the group velocity of light offers a broadband solution to a necessary functionality in microwave and millimeter wave systems.

TL;DR: In this paper, angle-resolved photoluminescence spectroscopy was used to obtain a comprehensive picture of the energies and field distributions of modes in the photon band gaps.
