Fabrication and optical characterization of photonic crystal quantum cascade lasers at terahertz frequencies
(2005)2005 Pacific Rim Conference on Lasers and Electro-OpticsWe will present the fabrication process and laser characterization of electrically contacted photonic crystal quantum cascade lasers emitting at 100μm. Using photonic crystals as reflectors enables monomode emission with low threshold currents.Conference Paper -

Transport and absorption in strain-compensated Si/Si1-xGex multiple quantum well and cascade structures deposited on Si0.5Ge0.5 pseudosubstrates
(2005)Materials Science in Semiconductor ProcessingVarious strain-compensated Si/SiGe quantum well structures with high Ge concentrations in the SiGe wells (70–85% Ge) have been successfully deposited by very low-temperature molecular beam epitaxy on thick strain-relaxed Si0.5Ge0.5 buffer layers. The samples have been subject to intensive and careful characterization of their structural, electronic and optical properties. X-ray diffraction and reflectivity measurements using synchrotron ...Conference Paper -
Multi-hopping induced gain scheduling for wireless networked controlled systems
(2005)Proceedings of the 44th IEEE Conference on Decision and Control, and the European Control Conference (CDC-ECC '05)A multi-hopping induced gain scheduler for Wireless Networked Controlled Systems (WiNCS) is proposed. The control scheme is based on a client. serv er architecture. The data packets are assumed to be carried over a network composed of wireless sensor nodes running the 802.11b protocol. The number of hops necessary for packets to reach their destinations is variable and depends on current traffic conditions. Changes in the number of hops ...Conference Paper -
Parallel estimators and communication in spacecraft formations
(2005)IFAC Proceedings Volumes ~ Proceedings of the 16th IFAC World CongressThis paper investigates the closed-loop dynamics of systems controlled via parallel estimators. This structure arises in formation flying problems when each spacecraft bases its control action on an internal estimate of the complete formation state. For LTI systems a separation principle shows that the necessary and sufficient conditions for overall system stability are more stringent than the single controller case; the controllers’ ...Conference Paper -
