Visit-to-visit blood pressure (BP) variability is an important predictor of stroke. However, which antihypertensive drug combination is better at reducing visit-to-visit BP variability and therefore at reducing stroke incidence remains uncertain. We have previously reported that the dihydropyridine calcium channel blocker benidipine combined with a… (More)
New waveguide technologies, namely direct bonding and dry etching, have improved damage resistance, transparent wavelength range, efficiency, and functionality. An engineered QPM structure enables variable wavelength conversion and reduces waveband crosstalk.
80-Gbit/s (20 Gbit/s/spl times/4) optical time-division multiplexing is demonstrated using an optical time-division multiplexer based on a hybrid integrated planar lightwave circuit. Each channel signals independently modulated by mixing in semiconductor optical amplifiers.
We have developed a new high-speed 32-channel optical wavelength selector (OWS) with gate drivers using PLC hybrid integration. It has excellent characteristics consisting of a low insertion loss of 2.3 dB, a low cross talk of -46 dB and the error-free optical wavelength selection of 10-Gbit/s optical signal.
