Chirped biphotons and their compression in optical fibers.
We show that broadband biphoton wave packets produced via spontaneous parametric down-conversion in crystals with linearly aperiodic poling can be easily compressed in time using the effect of group-velocity dispersion in optical fibers. This result could foster important developments in quantum metrology and lithography.
