All-Optical Signal Processing and Routing with Spectral Control by a High- Resolution Arrayed-Waveguide Grating
We proposed and designed novel arrayed-waveguide gratings (AWGs) for time-to-space (T-S) conversion-based high-speed optical signal processing. Recently, the frequency selectivity of AWGs has been considerably improved, offering the possibility of powerful tool for the manipulation of optical spectra. An arrayed-waveguide grating was fabricated, integrated with a 90 degree deflecting mirror. Mo...
متن کاملDesign of Optical Demultiplexer using Arrayed Waveguide Grating
Optical demultiplexers are used to receive multiple frequency signal from an optical fiber and to split it into its different frequency components. Arrayed waveguide gratings can be used to design an optical demultiplexer and works on the principle of interferometry. This paper presents the design of optical demultiplexer for an optical signal composed of eight frequency components. Simulation ...
متن کاملSpace-time Blind Signal Processing for Wireless Communication Systems
In this chapter we review recent advances in space-time processing techniques for wireless communication systems. Our emphasis is on blind methods for channel identiication and signal demodulation for the receive problem. We focus mainly on the multiple user problem and provide an in-depth discussion of several approaches for exploiting signal structure in order to recover the user signals.
متن کاملDesign of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks
This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
متن کاملArrayed Waveguide Grating Router
This paper discusses design, fabrication, and characterization of a 512 × 512 arrayed waveguide grating router (AWGR) with a channel spacing of 25 GHz. The dimensions of the AWGR is 16 mm × 11 mm and is fabricated on a 250 nm silicon-on-insulator platform. The measured channel crosstalk is approximately −4 dB without any compensation for the phase errors in the arrayed waveguides. The AWGR spec...
