The impact of optical feedback on the direct performance of a monolithic InAs/GaAs quantum dot passively mode-locked laser intended for applications such as multigigahertz interchip/intrachip clock distribution is experimentally investigated. Evaluation of the feedback resistance is an important feature, as the laser is to be monolithically integrated on(More)
—In this article, a printed ultra-wideband (UWB) monopole antenna with dual band-notched characteristics of size 26 mm × 35 mm is presented. The prototype consists of pincers-shaped radiation element and corner rounded ground plane. By inserting a pair of flexuous slots on the radiation element and a C-shaped slot on the ground plane, the 3.5/5.5 GHz dual(More)
The first monolithic GaInNAsSb quantum well 1.55 mm passively modelocked lasers grown on a GaAs substrate are reported. A repetition rate of up to 13.2 GHz and an optical pulse width as small as 26 ps have been realised. Introduction: The compact size, low power consumption, and direct electrical pumping of monolithic modelocked lasers (MLLs) make them(More)
Bischofia polycarpa (Levl.) Airy Shaw witches’-broom disease is widespread in southern China. Infected trees show symptoms of severely proliferating shoots, reduced leaf size, yellowing and reddening of leaves, and internode shortening. We detected the phytoplasma in diseased tissues by 4′,6-diamidino-2-phenylindole-HCl fluorescence microscopy and(More)
—Aiming at improving the radiating characteristics (pattern and polarization) and simplifying the design of feeding network, a new approach is applied and discussed. For uniformly excited planar antenna array, by rotating each element in its local coordinates and determining the rotation angles of the elements, the 3D radiating characteristic of the planar(More)
— Thermal management of devices package is now a critical problem for applications of high power light emitting diodes (LEDs). In this paper coppers were first electroplated on the novel package red, green, and blue LED chips directly. With the copper plating layer, the endurable injection current of these LED chips can be increased easily from conventional(More)
