We present the first room temperature photodection of hundreds on nanowatts using a quantum well mid-infrared detector at 9μm, with a background-limited temperature of 82K and a corresponding background-limited specific detectivity of 1.4×1010 cmHz1/2/W. The photonic architecture consists of an array of double metal nano-antennae and allows to reduce the dark current and increase the absorbed electromagnetic...
A digitally tunable optical power control loop with dynamic range >25dB is designed to compensate losses in large port count multi-stage switch fabrics. At 10 Gb/s with 7.7dBm of input power, the BER is 6.95×10-12.
Current technology scaling is leading to increasingly fragile components, making hardware reliability a primary design consideration. Recently researchers have proposed low-cost reliability solutions that detect hardware faults through software-level symptom monitoring. SWAT (SoftWare Anomaly Treatment), one such solution, demonstrated with microarchitecture-level simulations that symptom-based solutions...
This paper investigates the electric field and current density induced in a human body when exposed to low frequency electromagnetic fields. A numerical technique based on the Finite Element Method and electromagnetic quasistatic approximations is employed to compute both the fields generated by low frequency sources and the fields induced inside a human body due to exposure or contact. Case study...
This paper investigates the electric field and current density induced in a human body when exposed to low frequency electromagnetic fields. A numerical technique based on the Finite Element Method and electromagnetic quasistatic approximations is developed to compute both the fields generated by low frequency sources and the fields induced inside a human body due to direct or indirect exposure scenarios...

Polymer microring resonators have been exploited for high-sensitivity and wideband photoacoustic imaging. To demonstrate high-sensitivity ultrasound detection, highfrequency photoacoustic imaging of a 49-μm-diameter black bead at an imaging depth of 5 mm was imaged photoacoustically using a synthetic 2-D array with 249 elements and a low laser fluence of 0.35 mJ/cm2. A bandpass filter with a center...
