In this paper, the electrical property of a geometric optimization with elliptical shape dimer nanoantennas has been studied. Numerical calculations are based on the method of finite-difference time-domain (FDTD). Three types of elliptical shape dimer nanoantennas with different geometrical parameters were considered, namely, horizontal dimer, parallel(More)
A new all-optical switch based on the local nonlinear metal-insulator-metal (MIM) plasmonic Mach-Zehnder interferometer (MZI) waveguides was proposed. We used the finite-difference time-domain (FDTD) method to simulate the proposed structure. The numerical show that the proposed local nonlinear MIM plasmonic MZI waveguide structure could really function as(More)
A cost-effective differential-mode packaging of the TO-46 VCSEL module is proposed. The optimal bonding-wire and package solution have been demonstrated through frequency-domain and time-domain simulations. The differential-mode modulation bandwidth of the VCSEL module of above 21 GHz is achieved and a clearly opening eye diagram of 25 Gbit/s is observed.(More)
We propose an ultra compact and low crosstalk triplexer based on the X-type photonic crystal structure. It has been shown that the striplexer with the size as small as 36&#x03BC;m<sup>2</sup> can be designed at &#x03BB;&#x003D;1.55&#x03BC;m, &#x03BB;&#x003D;1.49&#x03BC;m, and &#x03BB;&#x003D;1.31&#x03BC;m.
This paper demonstrated a multi-channel Wavelength-Division-Multiplexing (WDM) system using photonic crystal structures. The system consists of a waveguide that realized by a defect row of photonic crystal and high Q-value micro-cavities. Two-Dimension (2-D) Finite-Difference-Time-Domain (FDTD) method is performed for simulation in this paper. The results(More)
