High performance mid- and far-infrared quantum cascade lasers
(2004)2004 IEEE LEOS Annual Meeting Conference Proceedings (LEOS 2004)Low threshold and highly tunable mid-infrared lasers are demonstrated based on a bound to continuum active region. Tunable emission over more than 150 cm/sup -1/ have been achieved. Terahertz quantum cascade lasers based on a bound to continuum active regions combined with an optical phonon extraction. Operation up to 117 K is demonstrated.Conference Paper -
Simulation and comparison of different stirrer types inside a reverberation chamber
(2004)2004 International Symposium on Electromagnetic Compatibility (EMC)In this paper the simulation of various types of electromagnetic stirrers inside a reverberation chamber is presented. Several different stirrer designs and sizes are compared against each other, and the influence of the stirrer axis orientation (vertical versus horizontal) within the chamber is shown. Three-dimensional electrical field integral equation based method of moment full-wave simulations in the frequency domain are used for the ...Conference Paper -
Low-power-consuming 24-Gb/s multiplexer in 90-nm CMOS for optical transceivers
(2004)12th IEEE International Symposium on Electron Devices for Microwave and Optoelectronic Applications (EDMO 2004)In this paper, an integrated 2-to-1 selector multiplexer in 90-nm complementary metal-oxide semiconductor (CMOS) digital technology is presented. The multiplexer is based on a differential Gilbert-cell structure. Peaking inductors are used to improve the bandwidth. At a supply voltage of 1.2 V, a speed performance of 24 Gb/s is achieved. The circuit core consumes only 10 mA. Common drain output buffers allow measurements at 50 /spl Omega/.Conference Paper -

Treatment of arbitrary-shaped boundaries with the finite-volume time-domain (FVTD) method
(2004)Proceedings of 17th International Wroclaw Symposium on Exhibition on EMCThe use of unstructured meshes enables the Finite-Volume Time-Domain (FVTD) method to deal with arbitrarily shaped boundaries. A selection of different boundary conditions that can be applied to surfaces is presented in this paper: dielectric interfaces, ports, perfect conductors and absorbing boundaries. The successful treatment of arbitrarily shaped boundaries is proved on the basis of two examples. First, the simulation of a corrugated ...Conference Paper
