Tzyy-Jiann Wang Coupling Characteristics of High-Q Elliptical Microresonator on LiNbO3
Tzyy-Jiann Wang,Po-Ting Chen,Hung-Ye Chen,Huan Nu,

High-Q elliptical microresonators on LiNbO3 are fabricated and its coupling characteristics are studied. The coupling position of the tapered fiber determines the coupling characteristics and the transmission spectrum. Strong coupling occurs at the position with the smallest curvature radius due to longer extension of evanescent field. The measured maximum intrinsic and external Q factors are 2.4×104 and 1.1×105.

Jui-Hong Hsu The All-Optical Flip-Flop based on Multimode Interference Waveguide
Jui-Hong Hsu,Yaw-Dong Wu,Hsiu-Chuan Huang,

In this paper, we propose an all-optical flip-flop based on the MMI PCW. Through shifting the boundary waveguide of the control ports, we can make outgoing field propagate in output waveguide or not. The intensity profiles show snapshots optioned at different times. This present result demonstrates that RS flip-flop operation is possible by using double different waveguide’s width and a MMI coupler waveguide in a PCs platform. Note that if we have an RS flip-flop, we can realize various much complex logic processing based on it.

Abstract - This paper studies the dispersion relation of one-dimensional photonic crystal waveguide structure. Periodically arranged on both sides of the waveguide structure by a dielectric material (cladding), an intermediate layer sandwiched between the defect (core) formed. We use the plane wave expansion method to calculate the group velocity of the waveguide structure with different wavelengths to obtain a dispersion relation of the waveguide structures of different wavelengths.

Guan-yu Jhan Metal-Insulator-Metal Band-stop plasmonic filter based on nonlinear nanodisk resonator waveguide structure
Guan-yu Jhan,Yaw-Dong Wu,

In this article, we proposed a band-stop plasmonic filters based on metal-insulator-metal (MIM) nonlinear nanodisk resonators. The band-stop filter is made up of an MIM waveguide coupled to nonlinear nanodisk resonators. The band-stop of the proposed plasmonic waveguide structure can be easily manipulated by adjusting the geometrical parameters and coupled-aperture width of the nanodisk resonators. The results are obtained by a 2D finite-difference time-domain (FDTD) method. It would be a potential key component in the application of the plasmonic integrated circuits.

An all-in fiber Mach-Zehnder interferometer (MZI) is proposed by automatically fusion splicing a short section of hollow core fiber (HOF) to the end of a single-mode fiber (SMF) and sandwiching a section of HOF in two section of SMF. Due to the liquid crystal (LC) material has high electric fields sensitivity, a novel in-line MZI formed by a vertical alignment (VA) LCs-filled HOF is demonstrated as a voltage sensor. The voltage induced wavelength shifts of the interference fringes are experimentally monitored. The experimental results show that the wavelength-voltage sensitivity is ~0.0225 nm/V, the resonant wavelength blue shift 9 nm was achieved by the voltage from 0V to 400V.
