ABSTRACT
Several designs for codirectional couplers in planar photonic crystals etched into GaAs-based heterostructures were investigated both theoretically and experimentally. Two different numerical techniques, i.e., plane wave expansion and finite difference time domain, were used to calculate the coupling lengths. Both methods are shown to be in good agreement with the experimental results. The measured coupling lengths are in the order of 350 periods, leading to a physical length of the order of 80 μm, much smaller than what is achieved in classical integrated optics couplers.

    In this study, we propose a new type of photonic crystal band-pass and band-stop filter based on biperiodic structure. Usually two types of photonic crystal band-pass filters are utilized in optical circuit. In the first one Fabry-Perot cavities are used while in the second one cavity-coupled...

    A transfer line is a tandem production system, i.e. a series of machines separated by buffers. Material flows from outside the system to the first machine, then to the first buffer, then to the second machine, the second buffer, and so forth. In some earlier models, buffers are finite, machines...

    The paper investigated a composite photonic crystal patch antenna by using the method of finite difference time domain (FDTD). The results show that there exists a wave resonance state at 2.635 GHz, where the real part of the permittivity and permeability are all negative; its refraction index...

    Thin film dielectrics have broad applications, and the performance degradation due to charge trapping in these thin films is an important and pervasive reliability concern. It has been presumed since the 1960s that current transport in intermediate-thickness (IT) oxides (∼10-100 nm) can be...
