Abstract

The generation of high-quality self-similar ultrashort pulses at 1550 nm by tapering the photonic crystal
fibers (PCFs) is numerically demonstrated. We taper the PCF to achieve the exponentially decreasing
dispersion and exponentially increasing nonlinearity profiles, which turn out to be the fundamental requirements
for generating the chirped self-similar pulses. Further, we find that the chirped solitons could also be generated
with the other three possible exponential variations. Thus, for the first time, we attempt tapering the PCFs for
bringing in these exponentially varying dispersion and nonlinear profiles. We carry out the detailed pulse compression
studies for various decay rates of the dispersion profiles as the decay rates of dispersion depend on the
initial chirp and hence on compression factor, too. The unique feature of this pulse compressor lies in the fact that
the required length of the tapered PCF is about 20 times less than that of the previously reported pulse compressor
operating at 850 nm. © 2016 Society of Photo-Optical Instrumentation Engineers (SPIE) [DOI: 10.1117/1.OE.55.6.067108]
