nm). Their variation in this region reveals the effect
of nonlinear coefficient and peak power significantly.
When P increases from 10000 to 40000 m
-1
the
signal and idler wavelengths shift away from each
other. The phase-matching curves observed for
HMOF with two ZDW is as shown in Fig. 4(b). In
Fig. 4(b) the similar phase-matching curves were
observed between the first and second ZDW (1241
and 1269 nm) for different P values.

and (b) Hybrid microstructured optical fiber.
4 CONCLUSIONS
The HMOF has the bandwidth of 104 nm and it has
been shown that for the given set of nonlinearity
coefficient and peak power a parametric gain 33 dB
for step index fiber and 29 dB for HMOF can be
obtained. While, the phase-matching curves for the
step index and HMOF with two ZDW were
observed to be between their respective ZDWs. It is
concluded that for broad bandwidth it is very much
necessary to have very small values of
2
and
4
simultaneously.
