We present a new monolithic silicon photonics technology suited for integration with standard bulk CMOS processes , which reduces costs and improves opto-electrical coupling compared to previous approaches. Our technology supports dense wavelength-division multiplexing with dozens of wavelengths per waveguide. Simulation and experimental results reveal an… (More)
Hemodynamic, pulmonary, and renal variables were measured in 24 patients scheduled for major abdominal aortic operations. Control values were obtained before preoperative medications were given. All patients received 5% dextrose in Lactated Ringer's solution intraoperatively. Postoperatively, group 1 patients received 5% dextrose in water plus albumin,… (More)

We demonstrate the first photonic chip designed in a commercial bulk CMOS process (65 nm node) using standard process layers combined with scalable post-processing, enabling dense photonic integration with high-performance microprocessor electronics.
Accurate conversion of wideband multi-GHz analog signals into the digital domain has long been a target of analog-to-digital converter (ADC) developers, driven by applications in radar systems, software radio, medical imaging, and communication systems. Aperture jitter has been a major bottleneck on the way towards higher speeds and better accuracy.… (More)
Circulatory and respiratory effects of change of posture from sitting to supine were studied in 11 obese patients scheduled for gastric bypass operations. Patients were studied on the morning of operation before any medication was given. Average weight was 138.8 kg, 108.6 per cent above ideal weight. Change of posture from sitting to supine was associated… (More)
A simplified technique relating individual heparin dose to desired anticoagulant effect was used in 152 patients during cardiac surgery. Activated clotting time (act) was measured by semi-automated technique (Hemochron) before and after heparin, 200 U/kg I.V. Two point linear dose-response curve allowed calculation of any additional heparin required for… (More)
A novel post-processing fabrication technique, based on XeF 2 etching, has been developed to locally remove the silicon substrate beneath polysilicon waveguides, enabling integration of low-loss strong-confinement microphotonics into standard bulk-silicon CMOS process flows.
