Low-loss Si3N4 arrayed-waveguide grating (de)multiplexer using nano-core optical waveguides.
A 16-channel 200 GHz arrayed-waveguide grating (AWG) (de)-multiplexer is demonstrated experimentally by utilizing Si3N4 buried optical waveguides, which have 50 nm-thick Si3N4 cores and a 15 μm-thick SiO2 cladding. The structure with an ultra-thin core layer helps to reduce the scattering due to the sidewall roughness and consequently shows very low loss of about 0.4~0.8 dB/m. When using this t...
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 کاملLow-loss arrayed waveguide grating at 760 nm.
An arrayed waveguide grating (AWG) at 760 nm is demonstrated with an insertion loss smaller than 0.5 dB. Interface roughness and waveguide length errors contribute much more to scattering loss and phase errors at 760 nm than at longer wavelengths, thus requiring improved design and fabrication. This Letter details how this is achieved by minimizing interfacial scattering, grating side-order exc...
متن کاملLow Loss a thermal Arrayed Waveguide Grating (AWG) Module for Passive and Active Optical Network Applications
In the present paper, we have investigated parametrically and numerically the low loss a thermal arrayed waveguide grating (AWG) which is composed of lithium niobate (LiNbO3)/polymer/silica-doped hybrid materials on a silicon substrate module for Passive and active optical Network applications. The modeling has parametrically analyzed and investigated over wide range of the affecting parameters...
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...
