“…This enabled use of longer waveguide path difference of AWG fibres and was thus able to obtain a higher frequency resolution. Later Dragone et al expanded 1× N AWG device to an N × N device, namely the wavelength router, mainly used in multiwavelength network applications [7]. Zirngibl et al developed InP-based PHASAR-Demux, in 1992, which was suitable for photonic integrated circuits due to their higher refractive index contrast [8].…”

Abstract-This paper mathematically models the operation of Arrayed Waveguide Grating (AWG) based multiplexer (mux) and demultiplexer (demux) used in optical networks. In WDM networks, the optical mux and demux play a crucial role of managing the aggregation and segregation of wavelengths for networking applications. A simple and intuitive model of AWG based mux design is discussed in this work. This model assumes that the device is linear, in which the principle of superposition is valid, and the primary emphasis is given to the optical power gain of the individual wavelengths. By using this model, one can exactly estimate the individual and overall power associated with each of the multiplexed wavelengths. The developed model was evaluated with experimental results using AWG based multiplexers. The experiments were repeated for different test cases with various power input levels and multiplexer configurations. It was found that the developed model provided a good approximation to the actual AWG mux/demux.

Abstract-Wavelength division multiplexed point-to-point transport is becoming commonplace in wide area networks. With the expectation that the next step is end-to-end networking of wavelengths (in the optical domain without conversion to electronics), there is a need for new design techniques, a new understanding of the performance issues, and a new performance evaluation methodology in such networks. This paper describes approaches to that end, summarizes research results, and points to open problems.

“…Traditionally fabricated on silica on silicon integration technology (Dragone et al 1991), it is possible to find examples of AWGs in almost any material platform (indium phosphide, silicon on insulator, silicon nitride, aluminium gallium arsenide…). The cost in photonic integrated circuits (PICs) is directly related to its footprint (Kirchain and Kimerling 2007), so technologies with higher index contrast where the field is highly confined in the waveguide and bending radius can be decreased are preferred to obtain smaller devices with the same functionality.…”
