Accurate model of depressive lines

A novel optical delay line based in an AWG and dispersive fibre is proposed and a detailed model provided. The model allows first to predict the performance of the device from the physical parameters defined in the design stage, and secondly the performance of the delay line when used as a building block to implement optical beamforming networks, photonic microwave filters or other optical signal processing devices.

This result allows to accurately design an optical true-time delay line based in AWGs. This delay line can be used as building block to implement optical beamforming networks, photonic microwave filters or, in general, optical signal processing functionalities. Photonic signal processing has many advantages, such as low loss and size, high dynamic range, extremely huge bandwidth, among others. The model allows fixing the design parameters to optimise the performance of the optical delay line.
