D. Dragoman et al., Implementation of the spatial and the temporal cross-ambiguity function for waveguide fields and optical pulses, APPL OPTICS, 38(5), 1999, pp. 822-827
On the basis of space-time duality, we propose experimental setups to imple
ment the cross-ambiguity function optically in space and time in one and tw
o dimensions. In space the cross-ambiguity is shown to be related to the co
upling efficiency between butt-joined optical waveguides. In time it is rel
ated to the spectrogram or the frequency-resolved optical gating techniques
for the characterization of optical pulses. (C) 1999 Optical Society of Am
