Image of FIG. 1.
FIG. 1.

Bragg MQW structure with a structural defect at the center. The thick arrow refers to the probe field and the thin arrows to the control field.

Image of FIG. 2.
FIG. 2.

Reflection (solid lines) and transmission (dotted lines) of the MQW system for various intensities of the control field ( in ) when ). (b), (d), and (f) represent the corresponding intensity wave patterns associated with (a), (c), and (e), respectively, along the structure when the photon energy of the probe is 1.549 eV (arrows). The dashed line in (e) refers to the response of the system when excitonic effects are ignored (off-resonant response). and are the amplitudes of the forward and backward waves in the structure.

Image of FIG. 3.
FIG. 3.

Patterns of optical field intensities inside the MQW structure for 1.549 eV and different IR laser intensities. Solid line corresponds to , dashed line to , and dotted line to . All conditions are the same as those in Fig. 2.

Image of FIG. 4.
FIG. 4.

Reflection of the MQW system for various intensities of the control field ( in ) with a structural defect . The dashed line in (d) refers to the off-resonant PBG response of the structure in the absence of the excitons. Here .

Image of FIG. 5.
FIG. 5.

Intensity patterns of the optical field inside the MQW structure corresponding to Fig. 4. The probe intensity is 1.552 eV [arrow in Fig. 4(a)].

Image of FIG. 6.
FIG. 6.

Intensity patterns of the optical field inside the MQW structure corresponding to Fig. 4. Here the probe intensity is considered 1.558 eV [arrow in Fig. 4(d)].

Image of FIG. 7.
FIG. 7.

Time delay associated with the cases shown in Figs. 4(a), 4(b), and 4(d). All conditions are the same as Fig. 4. The dotted-dashed lines refer to the corresponding transmission and the vertical dashed and dotted lines represent, respectively, 1.552 and 1.558 eV energies.
