Optical Leaky Wave Antenna with Ellipsoid Holes Array in Fourlayer Plasmons Structure
Based on the fourlayer plasmons structure (siliconmetalsiliconsilica), two types of optical leakywaveantennas that have different ellipsoidhole array structures in the metal layer were proposed. The structures include onedimensional symmetric tapered array and twodimensional symmetric tapered array. Based on antenna theory and finite element method, some physical characteristics for the antennas were investigated numerically. It is found that when the operating wavelength is fixed at 1550nm, the two antennas appear ultra wide bandwidth with 80 THz that covers the band of S+L+. With their ports filled in the air and the silicon nitride, respectively, they both show low return loss and insertion loss. But for two types of different filled materials, their characteristics show some differences, for example, in a onedimensional symmetric structure, the antenna has less return loss and insertion loss, lower side lobe level, and better directionality when its ports is filled with silicon nitride. The antenna can be generalized to apply in the fields of optical integrated interconnection, the control of highly integrated optical beam and space optical communication.
