15 صفحه اولComparative Analysis of AWG Demultiplexer and Chirped FBG based Demultiplexer in WDM PON Network
In Wavelength Division Multiplexing based Passive Optical Network (WDM-PON), multiple wavelength used to separate Optical Network Unit (ONU). Which actually increase the capacity of PON . WDM process can be dense and ultra-dense depending on channel spacing. In this paper we compare performance of Array Waveguide Grating Demultiplexer (AWG DEMUX) and Fiber Bragg Grating based Demultiplexer (FBG...
متن کاملDesign and performance of AWG multiplexer / demultiplexer in WDM systems
This paper addresses the design of arrayed waveguide grating (AWG) devices from the viewpoint of –3dB bandwidth and free spectral range. A straightforward numerical method of obtaining the physical dimensions of a real device for given – 3dB bandwidth and free spectral range is presented. The paper assesses also the influence of the –3dB bandwidth of the AWG on the performance of a dense wavele...
متن کاملTwo Dimensional Photonic Crystal based Four Channel Demultiplexer for ITU.T.G 694.2 CWDM Systems
In this paper, four channel demultiplexer is designed using two-dimensional photonic crystal for Coarse Wavelength Division Multiplexing applications. The proposed demultiplexer consists of bus wave guide, output wave guide and a cavity. The channel selection is done by having a cavity with unique refractive index. The two dimensional finite difference time domain and plane wave expansion metho...
متن کاملBirefringence compensated AWG demultiplexer with angled star couplers.
A new approach to birefringence compensation in arrayed waveguide gratings (AWG) is proposed. The star couplers are designed according to Rowland circle construction with an oblique incident/diffraction angle, similar to the case of an echelle grating. Such an AWG design is more general and flexible, and the conventional AWG becomes its special case when the grating angle is zero. By appropriat...
