FIG. 1.

Schematic experimental setup: fiber coupler, FC. Inset shows the optical micrograph of the PCF used in our experiment.

FIG. 2.

Observed cross correlations of coherent (dotted curves) and arbitrary (solid curves) pulses, at , transmitted through the fiber of (a) 0.0 and (b) in length. Horizontal axis, labeled in ps, for each graph is the absolute delay time. The additional axis in the bottom displays a retarded delay time, in which the origin is taken at the temporal COE of coherent pulse with corresponding length of PCF. In absolute delay, temporal COEs for coherent pulses transmitted through different lengths of fiber are (a) 0.0 and (b) , while the corresponding temporal COEs for arbitrary pulses are indicated by downward arrows. The cross correlation is seen to widen and deform significantly, evolving into several additional peaks as shown in (b).

FIG. 3.

Observed cross correlations for four different shapes (solid curves) of arbitrary pulses transmitted through a fiber of in length. In the time axis, the origin is taken at the temporal COE of coherent pulse (dotted curve) transmitted through the fiber, while the downward arrows indicate the COEs for transmitted arbitrary pulses.

FIG. 4.

Observed propagation delays (solid circles) and pulse durations (FWHM) (open circles) as a function of fiber length. The solid line indicates the net group delay calculated from Eq. (2). The dashed line (attached to solid one) indicates the calculation down to the zero length of the fiber. The dotted line shows the transmitted pulse broadening (FWHM) calculated from Eq. (3).
