A self-collimation splitting sensor truncated in a two-dimensional (2D) photonic crystal has been proposed and demonstrated theoretically. Intensity of transmitted light and reflected light, which varies with the width of the splitter, is detected at two output ports. Calculation results validated by the 2D finite-difference time-domain technique show that with the increase of width, the transmittivity decreases while the reflectivity increases and their summation decreases. Considering the trade-off between the sensitivity of the optical detector and the loss of power, including the difficulty of fabrication, the width of 0.4a is meet for the sensor. The simulated relative intensity monotonously increases from 1.63 to 2.94 nonlinearly.

AbstractIn this paper, an optical power divider with one input and four outputs has been proposed in a two-dimensional photonic crystal with triangular lattice and simulated using dielectric holes in an air substrate. The dividing properties of the power divider have been numerically simulated and analyzed using the plane wave expansion and finite difference time domain methods. The results show that the transmittance of this divider can be as high as 94.22 % for

We proposed a photonic crystal(PC) cavity of hexagonal lattice with six air holes of which the radius are different from other cylinders. In the center of this structure, the cavity can be obtained and light confinement is achieved. The Figure of E vs time apparently demonstrates that the light confinement can be observed in ultrafast time. All the Figures in this paper, calculated by 3D finite-difference time-domain method, illuminate that the structure proposed is significant in the field of PC.
