“…Here we give a sensitive example, an asymmetric 1D PC with five coupled defects [22]. The structure of this asymmetric 1D PC with five coupled defects is 7 , where n D d D = k 0 /2 and the other parameters are the same as above.…”

“…The representative examples of phenomena related to phases of PC are superluminal (faster-than-light) or slow light [15][16][17] and micro-cavity [18]. Recently, some measurements of PC phase have been reported [19,20]; and some photonic crystal phase devices have appeared [21,22]. The phase properties of PC above demonstrate that it is possible to use PC to modify the phase of laser.…”

“…These two problems are the rapid change of the light intensity around the defect mode and the influence of the substrate. The method for overcoming these problems is to construct the defective photonic crystal into a heterostructure or an asymmetric structure [15], as shown in Figure 1. A phase modulator and a phase switch with very high sensitivity (the sensitivity of a phase-control device can be hundreds of times higher than those using amplitude-control as the same coupled defect PCs are used) have been reported [15].…”

“…The method for overcoming these problems is to construct the defective photonic crystal into a heterostructure or an asymmetric structure [15], as shown in Figure 1. A phase modulator and a phase switch with very high sensitivity (the sensitivity of a phase-control device can be hundreds of times higher than those using amplitude-control as the same coupled defect PCs are used) have been reported [15]. Figure 1 shows the results as follows: when a single defect is induced into a 1D PC, a defect mode with a triangular single peak will appear in the band gap, as shown in Figure 1(a), and around the defect mode its phase-shift is 2, as shown in Figure 1(c).…”

“…Surprisingly, in a heterostructure or asymmetric structures, the intensity of reflective light at the middle of the defect mode approaches zero (almost without transmission loss), as shown in Figures 1(b) and (e); but the phase-shift is still 2 for every subpeak, as shown in Figures 1(c) and (d). This becomes the basis of phase devices [15].…”

Total optical phase logic gates are reported in this paper. They are constructed by coupled-defect photonic crystal after two problems are overcome by a heterostructure or an asymmetric structure. Both half and all-phase logic gates are discussed. The sensitivity of these total optical phase logic gates not only are two orders sensitive than those using amplitude-signal, but also have many other advantages: such as very low energy cost. By using such phase logic gates, only a continued wave laser with one frequency is sufficient to operate the phase logic gate or the whole optical integrated circuit.

In this article, through the optimized arrangement of the magnetized plasma, dielectric, and nonlinear Kerr dielectric, a tunable reflection phase retarder with a certain bandwidth is investigated. When the electric field of the incident electromagnetic wave is parallel to the xoy plane and has an angle of 45°with the x-axis, the electric field can be further decomposed into E x and E y along the xand y-axes, indicating TM and TE waves, respectively. The results show that under reasonable parameters, the 180°or −180°phase delay of the reflected wave of the proposed structure is obtained and adjusted. In particular, the nonlinear bistable response at this performance is also demonstrated. Furthermore, to verify the superiority of the obtained bandwidth of the phase retarder, the influences of the incident angle, the plasma frequency, the external magnetic field, and the nonlinear light intensity on the bandwidth of the phase retarder have been studied. It is observed that the total phase retarder bandwidth can reach 2.6 GHz by appropriately optimizing those parameters. Additionally, this work provides constructive suggestions for tunable broadband phase blockers and half-wave plates, and it still holds some potential significance in the radome.
