We propose optimal designs for triply-resonant optical parametric oscillators (OPOs) based on degenerate four-wave mixing (FWM) in microcavities. We show that optimal designs in general call for different external coupling to pump and signal/idler resonances. We provide a number of normalized performance metrics including threshold pump power and maximum(More)
Near-infrared Hong-Ou-Mandel quantum interference is observed in silicon nanophotonic directional couplers with raw visibilities on-chip at 90.5%. Spectrally-bright 1557-nm two-photon states are generated in a periodically-poled KTiOPO 4 waveguide chip, serving as the entangled photon source and pumped with a self-injection locked laser, for the photon(More)
We demonstrate the temporal and spectral evolution of picosecond soliton in the slow light silicon photonic crystal waveguides (PhCWs) by sum frequency generation cross-correlation frequency resolved optical grating (SFG-XFROG) and nonlinear Schrödinger equation (NLSE) modeling. The reference pulses for the SFG-XFROG measurements are unambiguously(More)
Cytomegalovirus (CMV)-associated gastroduodenal ulcers (GDU) are a rare digestive disease, which principally affect immunocompromised patients. We recently experienced CMV-associated GDU occurring in a seemingly immunocompetent patient. The rarity of such a condition was inimical to a correct clinical diagnosis.A 77-year-old woman with Alzheimer's disease(More)
This report describes a new procedure for examining functional deafness with binaural sound stimulation. This new hearing test can estimate the genuine pure tone hearing threshold quantitatively at every frequency by using the ordinary audiometer. In the case of the nonorganic deafness, even if the hearing disorders are bilateral or hemilateral, we believe(More)
