— Optical burst switching (OBS) is one promising method for data transfer in photonic networks based on a WDM (Wavelength Division Multiplexing) technology. In the OBS scheme, the wavelength is exclusively reserved along the source and destination nodes, when the burst data is generated at the source. Then, efficient data transfer is expected. However, its(More)
The performance of the phase-shifted superstructured fiber Bragg grating (SSFBG) for optical code (OC) recognition was investigated with different reflectivity as well as input pulse width. The auto-correlation peak (PA) and the ratios of PA to the maximum wing level (P/W) and cross-correlation level (P/C) were used to quantitatively evaluate the OC(More)
SUMMARY Optical code division multiplexing (OCDM) is the other class of multiplexing techniques than time division mul-tiplexing (TDM), wavelength division multiplexing (WDM) and space division multiplexing (SDM). OCDM has been proposed in mid '70s. It has been long since OCDM remains outside the mainstream of research community of optical communications,(More)
—Lightwave networks realized through code division multiple access techniques are extensively studied to determine their ultimate capabilities. Here, these concepts are extended to network implementation by introducing an optical code division multiplexing (OCDM) multihop strategy using optical coding. It is shown that this approach is effective in scaling(More)
The generation and recognition of a record-length 511-chip optical code is experimentally demonstrated by use of a superstructured fiber Bragg grating (SSFBG) with a chip rate of 640 Gchips/s. Very high reflectivity (92%) is achieved with high-quality correlation properties. The temperature deviation tolerance is approximately +/- 0.3 degrees C, which is(More)
This paper explores different functionalities that can be implemented directly over the optical layer, paving the way for the future for converged wireless and wired services optical networks. Wireless technologies operating over optical networks mainly employ radio-over-fiber (RoF) technologies, which effectively help to manipulate microwave and(More)
An energy-efficient, high-performance optoelectronic packet switching for intra-data center (DC) network is presented, in which hybrid optoelectronic packet routers (HOERs) are interconnected with 100 Gbps (25 Gbps×4 wavelengths) links. A novel “Express path (ExP)” is introduced to enable the flow control. Packets, which are a part of a(More)
