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)
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 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)
