“…A little change of the excitonic resonant frequency will lead to the collapse of band gap, which induces a reflective or transmitted light intensity change, consequently forming a transmitted and reflective optical switch [8] . Transfer matrix approach [9] is used to investigate the stop band (reflection) of 200-periods In 0.53 Ga 0.47 As/InP BSQWs with excitonic wavelength of 1.5 μm. By inducing the excitonic susceptibility and effective optical thickness to consider the influence of light polarization and incident angle, this approach is capable of simulating accurately the band structure of 1D RPC.…”

Citation: Wang T, Li Q, Gao D S. Ultrafast polarization optical switch constructed from one-dimensional photonic crystal and its performance analysis.All-optical switch with the ultrafast optical switching rate is a key device in the next generation optical network. In this article, we propose a polarization switch with ps switching time, which is constructed from one-dimensional resonant photonic crystal (1D RPC). The model of switch operating at 1.5 μm is established based on the optical stark effect (OSE). We calculate the performance indices of the switch and the influences of errors of periods and refractive index on the performance characteristics.all-optical switch, 1D resonant photonic crystal, optical stark effectThe great revolution of telecommunication makes it an inevitable trend to replace the dominant position of circuit switching mode by the optical packet switching. The capacity of network communication will be enhanced by employing the technology of WDM (wavelength division multiplexing) or TDM (time division multiplexing). Especially, the switching rate will be increased to the level of Tbit/s. The rate of conventional electric-driven switches is limited by the inherent characteristic of electron. Hence it is greatly important to investigate the ultrafast optical switches based on the new mechanism to satisfy the need of Tbit/s.Recently, the study of spin relaxation switching in multiple quantum wells (MQWs) semiconductor has made significant progress [1][2][3][4] . Whereas, it is difficult to increase the switching repetition rate as several hundred picoseconds are required for the recombination of resonant-excited carriers. Gansen et al. [5] demonstrated that with the pump pulse tuned near the heavy-hole excitons, virtual excitons would exist within the pump pulse time (about hundreds of femtoseconds or a few picoseconds), which improved the switching repetition rate and shortened the switching time to several picoseconds. However, it was also shown that this optical switch was difficult to implement due to the high power of the pump pulse and large insert loss [5] . To solve this problem, Prineas et al. [6] made a breakthrough in investigating the ultrafast suppression and recovery of one-dimensional resonant photonic crystal (1D RPC) band-gap structure from InGaAs/GaAs Bragg-spaced quantum wells (BSQWs) by employing the mechanism of AC stark effect. However, the investigation by Prineas et al. only adopted InGaAs ternary compound as the active bandgap material. We extended this principle to 1.5 μm compatible with optical fiber network. Beginning from the calculation of 1D RPC band gap, the physical mechanism of band gap suppression induced by optical stark effect (OSE) is analyzed and the switching performances are calculated by using the transfer matrix approach. Then, the influence of errors of period and refractive index on the performance index is considered.

“…The basic difference is that higher Q-values are expected to be achievable for individual defect modes in case of multilayers. In turn, the theories of graded-index rugate frequency filters [9][10][11][12], thin-film multilayer frequency filters [13], and onedimensional PCs [14][15][16][17] should provide one with the initial guidelines for obtaining a desired angle dependence of transmission. However, although the existing frequency-domain transmission results might give some ideas for obtaining a desired spatial filter, they do not allow one understanding some important points like 0030 angle-domain multibandness.…”

a b s t r a c tThe potential of one-dimensional, periodic, graded-index, isotropic dielectric lattices with defects in multiband spatial and spatial-frequency filtering is studied. It is shown that both narrow-and wide-bandpass filters can be obtained at a proper choice of the number, location, and parameters of the defects placed inside the relatively thin slabs. The peculiarities of achieving multibandness for narrow-and wide-bandpass filters are discussed. Multiband narrow-bandpass filtering is closely related to the transmission features that are associated with Fabry-Pérot resonators with semitransparent planar mirrors. Correspondingly, the observed transmission can be interpreted in terms of the equivalent parameters of such resonators. In particular, it is shown that the resonators filled with an ultralow-index medium can be mimicked, so that defect-mode angle-domain spectrum can be rarefied at large angles of incidence. The obtained results are also expected to be applicable for prediction of the angle-domain behavior of transmission in case of piecewise-homogeneous multilayers.

“…Since the layers are nonmagnetic, their permeabilites are = = 1. The transfer matrix approach was used in order to investigate the band-gap of semiconductor MQWs [15]. Suppose that an electric wave (E), along the -direction, is normally (along the -direction) incident on the structure as shown in Figure 1.…”

This study examined MQWs made of InGaAs/GaAs, InAlAs/InP, and InGaAs/InP in terms of their band structure and reflectivity. We also demonstrated that the reflectivity of MQWs under normal incident was at maximum, while both using a strong pump and changing incident angle reduced it. Reflectivity of the structure for a weak probe pulse depends on polarization, intensity of the pump pulse, and delay between the probe pulse and the pump pulse. So this system can be used as an ultrafast all-optical switch which is inspected by the transfer matrix method. After studying the band structure of the one-dimensional photonic crystal, the optical stark effect (OSE) was considered on it. Due to the OSE on virtual exciton levels, the switching time can be in the order of picoseconds. Moreover, it is demonstrated that, by introducing errors in width of barrier and well as well as by inserting defect, the reflectivity is reduced. Thus, by employing the mechanism of stark effect MQWs band-gaps can be easily controlled which is useful in designing MWQ based optical switches and filters. By comparing the results, we observe that the reflectivity of MWQ containing 200 periods of InAlAs/InP quantum wells shows the maximum reflectivity of 96%.
