Despite the high phase non-linearity of a Silicon Mach-Zehnder Modulator in forward bias, we demonstrate that high third order spur-free dynamic range ~102.8 dB. Hz2/3 can be obtained by optimizing the D.C. bias operating point at 1 GHz.
We demonstrate InP based evanescently-coupled p-i-n photodiodes heterogeneously integrated onto silicon-on-insulator substrate. Using advanced waveguide structures and fabrication processes, it simultaneously achieves 67 GHz O-E bandwidth (RC-free), broad optical window (1520–1600nm) with 0.5 A/W internal responsivity, and high saturation currents (9 mA at 70 GHz).
A novel silicon p-i-n diodes for detecting backscattering electrons in SEM was proposed and fabricated. The multi-annular configuration enables to provide better surface topography contrast of BSE image compared with traditional quadratic configuration. In this study, the multi-annular backscattered electron detector (BSED) can provide surface topography contrast of 82.11 nA/µm, which is 105% increase...
A variable inclined swirl system (VISS) was developed to generate in-cylider inclined swirl air motion in a four-valve SI engine, the in-cylinder inclined swirl characteristics generated by VISS were studied in steady flow rig, and the effect of inclined swirl characteristics on cyclic variation of combustion pressure were analyzed with combustion analyzer in engine test-bed. The steady flow results...
