We describe an experiment in which photon pairs from a pulsed parametric down-conversion (PDC) source were coupled into single-mode fibers with heralding efficiencies as high as 70%. Heralding efficiency or mode preparation efficiency is defined as the probability of finding a photon in a fiber in a definite state, given the detection of its twin. Heralding efficiencies were obtained for a rang...

Current mode circuits cover an important area of application like filters, neural networks and analog-digital conversion. Current mode circuits, because of their special structure, need appropriate methodology during design process. This paper is an overview of most common problems related with analog and mixed digital-analog converters and filters performed in a CMOS technology. Laboratory mea...
