“…PhCs have many attractive characteristics such as photonic bandgap (PBG), localization effect, and refraction effect. By introducing point defect and/or line defect, PhC-based devices can be made [2], such as PhC-based waveguide [3][4][5], nanocavity [6][7][8], low threshold lasers [9][10][11][12], PhC-based filter [13][14][15], PhC fibers [16][17][18][19], optical sensors, and so on.…”

Abstract:In this paper, we propose and simulate a pressure sensor based on two-dimensional photonic crystal with the high quality factor and sensitivity. The sensor is formed by the coupling of two photonic crystal based waveguides and one nanocavity. The photonic crystal with the triangular lattice is composed of GaAs rods. The detailed structures of the waveguides and nanocavity are optimized to achieve better quality factor and sensitivity of the sensor. For the optimized structures, the resonant wavelength of the sensor has a linear redshift as increasing the applied pressure in the range of 0 -2 GPa, and the quality factor keeps unchanged nearly. The optimized quality factor is around 1500, and the sensitivity is up to 13.9 nm/GPa.

“…Such tuning has previously been accomplished in a 2D PC laser by lithographically controlling the local cavity geometry 5 or by filling of the holes of the PC with liquids of different refractive index. 6 Until now, it has been difficult to actively tune the emission frequency of PC lasers by deliberately changing the refractive index of the material inside of the cavity.…”

An electrically tuned nematic liquid-crystal (LC) infiltrated photonic crystal (PC) laser is demonstrated. This PC laser represents an emerging class of nanoscale optical adaptive devices enabled by the convergence of nonlinear optical materials, electronics, and fluidics that promise increased functionality and utility over existing technologies. A LC cell is constructed by encasing the PC laser between two indium tin oxide glass plates, which serve as the modulating electrodes. Applying a voltage across the cell realigns the LC, modifies the laser cavity's optical path length, and blueshifts the lasing wavelength.

“…The so-called photonic band gap (PBG) structure has become a very important subject in the optics regime. For instance, nanometer and micron sized PBG devices are currently being explored to enhance the performance of microcavity laser mirrors and for their applications in a variety of optical systems associated with communications, data storage, and computing [1][2][3][4][5][6][7][8][9][10][11]. In the microwave area numerous research groups are using microwave band gap (MBG) structures, for example, to modify the frequency performance of microstrip lines, to suppress surface wave modes associated with microstrip fed patch antennas and to enhance the radiation characteristics of a variety of wire antennas [12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

Abstract-Metallo-dielectric electromagnetic bandgap (EBG) structures are studied in the millimeter regime with a finite difference time domain (FDTD) simulator. Several EBG waveguiding structures are considered for millimeter-wave power splitting, switching and filtering operations. It is demonstrated that triangular EBG structures lend themselves naturally to the design of Y-power splitters. Square EBG structures with circular and square rods are shown to lead naturally to straight in-line waveguide filter applications. Comparisons between EBG millimeter-wave waveguide filters formed with dielectric and metallic rods are given. It is shown that high quality broad bandwidth, millimeter-wave bandstop filters can be realized with square EBG structures with circular metallic rods. It is demonstrated that multiple bandstop performance in a single device can be obtained by cascading together multiple EBG millimeter-wave waveguide filters. It is also demonstrated that one can control the electromagnetic power flow in these millimeter-wave EBG waveguide devices by introducing additional local defects. It is shown that the Y-power splitter can be made reconfigurable by using imposed current distributions to achieve these local defects and, consequently, that a millimeter-wave EBG switch can be realized.
