The prognosis in surgical necrotizing enterocolitis (NEC) has focused on the total length of the resected bowel; the relative impact of small intestinal vs colonic resection is not well studied.We hypothesized that intestinal resections may reduce mo

Microwave photonic phase shifters based on stimulated Brillouin scattering (SBS) offer tunable and broadband, optically controllable phase shifts. However, achieving a 360° phase shift requires a large amount of SBS gain which often exceeds the avai

We present a wideband and arbitrarily reconfigurable photonic solution to RF equalization using the nonlinear optical phenomenon of stimulated Brillouin scattering (SBS). In this work, we equalize an RF photonic downconverter with optical signal proc

We review recent progress in applying stimulated Brillouin scattering to microwave photonic links in multiple signal processing contexts. Dynamic bandpass filters, high selectivity notch filters, and wideband phase shifters are demonstrated. These de
