A wavelength-selective 2-order 1-by-8-port optical multicast filter bank is demonstrated utilizing microring resonators, achieving ~2.6× faster roll-off than 1-order design while maintaining highly uniform responses among all eight drop ports. OCIS codes: (130.3120) Integrated optics devices; (230.5750) Resonators; (230.0250) Optoelectronics.

This paper presents a high-selectivity dual-band bandpass filter with independently-tunable passband frequencies. A tap-coupled structure is utilized to feed the two resonators at lower passband and a coupling structure is used to feed the two resonators at the upper passband. Two pairs of varactor-loaded resonators operating within two different frequency ranges, allow the independent passband...

Drilling into a rock massif is energetically extremely consumptive process. Hence the optimization of drilling regime with objective of energy consumption minimization, is very important. Proposed article discusses partial problem of this problem. During the drilling process it is useful to know the drilled rock type, whereas to particular drilled rock needs convenient drilling regime, which is...

In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

Abstract: As the device feature size enters into the nanoscale, the modeling and simulation of short channel effects in FinFETs devices become challenging. In this paper an easy approach to model short channel effects threshold voltage roll-off in nanoscale n-channel FinFETs is presented. The decrease of threshold voltage with decrease in gate length is a well-known short channel effect called ...

The trend to a world with ubiquitous electronics has the need for novel concepts sensors and actuators that are lightweight, flexible, low-cost, also sustainable. Piezoelectric transducers on basis of functional polymers can meet these expectations. In this work, concept paper-embedded large-area piezoelectric devices realized solely by means roll-to-roll (R2R) mass printing post technologies i...

The effect of pre-existing nano sized precipitates on the mechanisms and rate of grain refinement has been investigated during the severe plastic deformation. A binary Al–0.2Sc alloy, containing coherent Al3Sc particles, of 3.62 nm in diameter has been deformed by accumulative roll bonding up to 10 cycles. The resulting deformed structures were quantitatively analyzed using electron backscatter...
