Background
At present, the resistance to antibiotics is considered the most important reason for Helicobacter pylori (HP) eradication failure. The aim of this study was to estimate the prevalence of antimicrobial resistance of HP strains and to evaluate tailored and empiric therapeutic regimens in patients with peptic ulcer disease associated with infection of this microorganism.

Passband filtering and in-band crosstalk penalties are investigated using WSS filter shapes fitted using a supergaussian model and an analytical model. The analytical model is determined to be more accurate than the supergaussian model for stopband fitting and crosstalk penalty assessment.
We demonstrate an 11 port count wavelength selective switch supporting spatial superchannels of three spatial modes, based on the combination of photonic lanterns and a high-port count single-mode WSS.
We present a few-mode spectral pulse-shaper, that offers independent control over the spectral phase and attenuation of different input modes from a multi-mode input, with a similar performance to a single mode device.
