Silicon-on-insulator shortwave infrared wavelength meter with integrated photodiodes for on-chip laser monitoring [PDF]

, 2014
This paper demonstrates a very compact wavelength meter for on-chip laser monitoring in the shortwave infrared wavelength range based on an optimized arrayed waveguide grating (AWG) filter with an integrated photodiode array. The AWG response is designed

Improved AWG Fourier optics model

Optics Express, 2004
In this paper we present an improved Fourier Optics model to calculate the transmission characteristics between any arbitrary pair of input/output ports (IOPs) of an Arrayed Waveguide Grating (AWG). In this model the input and output sections of the AWG are modeled using the same approximations, thus removing some reciprocity-related inconsistencies ...

Optimized Silicon AWG With Flattened Spectral Response Using an MMI Aperture [PDF]

Journal of Lightwave Technology, 2013
We demonstrate compact 12-channel 400 GHz arrayed waveguide grating wavelength demultiplexers (AWG) in silicon with a flattened spectral response. Insertion loss, crosstalk and non-uniformity are -3.29 dB, 17.0 dB and 1.55 dB, respectively. The flattened

Comparison of AWGs and Echelle Gratings for Wavelength Division Multiplexing on Silicon-on-Insulator [PDF]

IEEE Photonics Journal, 2014
We compare the performance (insertion loss and crosstalk) of silicon-based arrayed waveguide gratings (AWGs) and echelle gratings for different channel spacings.

Modular AWG-based Optical Shuffle Network [PDF]

Asia Communications and Photonics Conference, 2017
This paper proposes an arrayed-waveguide grating (AWG) based wavelength-division-multiplexing (WDM) shuffle network. Compared with previous optical shuffle networks, our proposal is compact, easy to implement, highly scalable, and cost ...

Design of High-Precision Parallel AWG Demodulation System [PDF]

Micromachines, 2023
Here, we present a high-precision demodulation method that supports the arrayed waveguide grating (AWG) system, which includes a 1 × 8 AWG as the primary filter with a 0.5 nm channel spacing and a 1 × 4 AWG as the auxiliary filter with a 1 nm channel ...
