The V-BLAST (vertical Bell Labs layered space-time) architecture with equal rate and power per antenna and a fixed order of detection is known to suffer from poor performance; in a multi-input… (More)
Assuming that the channel state information is available at both transmitter (CSIT) and receiver (CSIR), we propose a novel multiinput multioutput (MIMO) transceiver design that combines the… (More)
Interband cascade lasers with type-I InGaAsSb/AlAsSb quantum well active regions were demonstrated. Ridge-waveguide devices exhibit room-temperature continuous-wave emission at 3.2μm, providing a… (More)
The far-field patterns of InAs-based plasmon-waveguide interband cascade lasers are experimentally and theoretically investigated. It is shown that different ridge waveguide structures and metal… (More)
InAs-based interband cascade (IC) lasers with dielectric-metal hybrid top cladding layers were demonstrated at emission wavelengths near 5.3 μm for temperatures up to 248 K in continuous wave mode… (More)
We report the demonstration of InAs-based interband cascade lasers at temperatures up to 315 K and 253 K operating in pulsed and continuous wave modes, respectively, near 5.3 microns.
A two-stage structure comprised of a regulated single-stage power factor correction (S/sup 2/PFC) AC/DC front end and an unregulated low-frequency DC/AC inverter is selected as a high-power-density… (More)
We report the demonstration of InAs-based interband cascade lasers in a temperature range from 80 to 260 K operating in pulsed and continuous wave modes at wavelengths near 6.0, 7.4, and 10.3 microns.
Pulsed and continuous wave operations of InAs-based interband cascade lasers were demonstrated at temperatures up to 377 and 308K, respectively, with low threshold current densities (278 A/cm2) at… (More)
InAs-based single-mode distributed feedback (DFB) interband cascade (IC) lasers were investigated. The DFB grating was patterned using interference lithography to etch the cladding-free upper… (More)
