Recognition of Wavelength-multiplexed Labels with Acoustooptic Waveguide Circuit for Hierarchical Photonic Routing

چکیده
High-speed optical processing for packet routing can overcome bottleneck in largecapacity photonic networks. We have studied on collinear acousto-optic (AO) switches and applications to optical label recognition. Since parallel combination of collinear AO switches can handle wavelength-division-multiplexed (WDM) optical pulses, recognition for optical labels encoded in spectral and time domains can be realized. In this report, we discuss recognition of layer-structure labels for hierarchical routing control. By employing WDM time-series labels including identifying bits, the labels corresponding to each layer can be recognized. The recognition characteristics are confirmed by computer simulation.

An optical fiber provides enormous capacity of more than tens terabits per second for transmission in photonic networks, whereas packet processing in network nodes will become a bottleneck for large-capacity networking. For realization of large-capacity and high-speed photonic networks, fast optical processing without conversion to electric signal is preferable (Seo et al., 1996; Blumenthal et ...

With unprecedented ability to localize electromagnetic field in time and space, the nanometer scale laser promises exceptionally broad scientific and technological innovation. However, as the laser cavity becomes subwavelength, the diffraction of light prohibits the directional emission, so-called the directionality, one of the fundamental attributes of the laser. Here, we have demonstrated a d...

In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...
