In this paper, we further improve the optical bandwidth of grating couplers, propose and experimentally validate a new and novel approach for wideband waveguide grating coupler design which can attain
In this paper, we compare the effect of output waveguide configurations on the performance of AWGs. The AWG with an output waveguide converging on the grating circle had larger crosstalk and lower
This leads to the first implementation of arrayed waveguide gratings on X-cut thin-film lithium niobate with various configurations and high-performances.
Optical loss, bandwidth, spectral resolution, transmission function shape, crosstalk, and polarization sensitivity are the most important performance parameters of an AWG spectrometer and for different
This leads to the first implementation of arrayed waveguide gratings on X-cut thin-film lithium niobate with various configurations and high-performances.
Array waveguide gratings (AWGs) have been widely used in multi-purpose and multi-functional integrated photonic devices for Microwave photonics (MWP) systems. In this paper, we
In this paper, we designed and demonstrated AWGs utilizing a 200-nm-thick-Si3N4-core platform with a moderate confinement factor (33 %) to realize relatively low-loss, low-crosstalk and small footprints.
In this review, an overview of the available methods for improving the bandwidth, spectral resolution, and transmission function shape of AWGs is provided. The working principle as well as the advantages
We compare the performance of silicon-based arrayed waveguide gratings (AWGs) with star couplers of Rowland and Confocal configurations, respectively, for both TE and TM polarizations.
A conventional AWG spectrometer with the same bandwidth and resolution values was realized to compare its performance with the interleaved AWG. Based on the measurement results, interleaved
