We comprehensively analyze multiple WDM channels RZ-to-NRZ format conversion using a single microring resonator. The scheme relies on simultaneous suppression of the first order harmonic components in the spectra of all the RZ channels. An optimized silicon microring resonator with free spectral range of 100 GHz and Q value of 7900 is designed and fabricated for this purpose. Multi-channel RZ-t...

40-Gb/s return-to-zero (RZ) transmission in strong dispersion maps is limited by single-channel four-wave mixing. Appropriate phase modulation of the signal suppresses generation of the ghost pulses. Duobinary and modified duobinary encoding produce cancellation of nonlinear interaction while carrier-suppressed RZ generates perturbations that add up coherently.

This paper demonstrates bandwidth requirement for optical DPQSK transmitter using one Dual-drive Mach Zehnder Modulator (DDMZM) for 100Gb/s physical transmission. The result shows that at receiver bandwidth of 40GHz, NRZDQPSK signal requires 60GHz modulation bandwidth at least, while RZ-DQPSK scheme demands less bandwidth, about 40GHz for 50% duty cycle RZ-DQPSK signal.

The long-term use of copper (Cu) fungicides in viticulture Europe has led to Cu accumulation vineyard top soils. However, less is known about the grapevine grafts after callusing process/before planting nursery. This paper presents capacity 5BB and SO4 rootstocks accumulate Cu, as well patterns translocation grafts. After heat forcing (callusing), Sauvignon Blanc on were grown pots for six mont...

Sixty rhizosphere soil samples of apple seedlings and rootstock were collected from six nurseries of Khuzdar and Kalat districts of Balochistan. Six different plant nematodes were found associated with the seedlings and rootstock. The most predominant nematode was Xiphinema americanum, whereas the nematode found from a single locality was Tylenchus butteus. A matrix of similarities with respect...

We describe a new optical phase erasure characteristic of periodically poled lithium niobate (PPLN) by using cascaded second-harmonic generation and difference-frequency generation with the signal set at the quasi-phase-matching wavelength. A simple analytical expression is derived clearly explaining the operation principle. It is interesting that the optical phase erasure feature enables an al...

The reproducible quality of phytopharmaceuticals--herbal medicines--is an essential prerequisite for good efficacy and tolerability in the treatment of functional disorders. In clinical trials and scientific investigations, standardized assessments (i.e., validated, internationally recognized and accepted scales) provide the basis for establishing clinical efficacy and tolerability. Extracts (e...

The objective of this study was to compare the growth of three Leucadendrons (Proteaceae) cultivars (`Safari Sunset', `Orot' and `Meir') fertigated with three levels of P. The plants were grown in tuff (pyroclastic material, characterized by high porosity) in 10 l pots and fertigated daily. The experiment included control treatment (plants irrigated with tap water) and three levels of P (0, 10 ...
