چکیده
Wavelength Division Multiplexing (WDM) plays an important role in optical interconnection. In this paper, a 16-channel WDM device is designed on Silicon-On-Insulator (SOI) substrate by using sub-wavelength grating (SWG) structure, which can cover O-band and C-band at the same time, output channel reversely coupled from main waveguide to realize wavelength demultiplexing. The simulation results show that loss of our demultiplexing less than 0.5 dB crosstalk 17 dB. When performed O-band, transmission bus 0.05 insensitive duty cycle, with good process tolerance. footprint 200 μm × 150 μm, size single-channel filter 2 large bandwidth compact structure.

Compact devices for wavelength division multiplexing and demultiplexing, believed to be novel, are presented. These devices are based on planar optics configurations, comprising multiplexed diffractive optical elements. The principle, design, and recording of these planar devices are described, including the fact that the recording is done at a single wavelength in the green region. Experimenta...
متن کاملWavelength division multiplexers/demultiplexers for high- throughput optical links
Communication between computing systems is recognized as the main limitation to increasing the speed of all-electronic systems beyond levels currently achieved in existing supercomputers. Optical interconnects hold great promise in eliminating current communication bottlenecks because of properties that stem from optics inherent parallelism. Wavelength-division multiplexing (WDM) technology, by...
متن کاملAll-optical LAN architectures based on Arrayed Waveguide Grating Multiplexers
The paper presents optical LAN topologies which are made possible using an Arrayed Waveguide Grating Multiplexer (AWGM) instead of a passive star coupler to interconnect stations in an all-optical LAN. Due to the collision-free nature of an AWGM it ooers the n-fold bandwidth compared to the star coupler. Virtual ring topologies appear (one ring on each wavelength) if the number of stations atta...
متن کاملEfficient wavelength multiplexers based on asymmetric response filters.
We propose integrated photonic wavelength multiplexers based on serially cascaded channel add-drop filters with an asymmetric frequency response. By utilizing the through-port rejection of the previous channel to advantage, the asymmetric response provides optimal rejection of the adjacent channels at each wavelength channel. We show theoretically the basic requirements to realize an asymmetric...

Dec 2000 News: * Claiming a world-best speed record for optical data transmission, researchers at Siemens have transmitted 7 Tbits/s over a single optical fiber using DWDM. That's the equivalent of over 100 million telephone calls or a billion pages of typed data per second. The demonstration was conducted by Siemens' Information and Communication Networks Group at the company's Advanced Optica...
