Fresnel diffraction effects in Fourier-transform arrayed waveguide grating spectrometer.
We present an analysis of Fourier-transform arrayed waveguide gratings in the Fresnel diffraction regime. We report a distinct spatial modulation of the interference pattern referred to as the Moiré-Talbot effect. The effect and its influence in a FT AWG device is explained by deriving an original analytical expression for the modulated field, and is also confirmed by numerical simulations usin...
متن کاملArrayed Waveguide Grating Router
This paper discusses design, fabrication, and characterization of a 512 × 512 arrayed waveguide grating router (AWGR) with a channel spacing of 25 GHz. The dimensions of the AWGR is 16 mm × 11 mm and is fabricated on a 250 nm silicon-on-insulator platform. The measured channel crosstalk is approximately −4 dB without any compensation for the phase errors in the arrayed waveguides. The AWGR spec...
متن کامل20GHz Channel Spacing InP-based Arrayed Waveguide Grating
We demonstrate a 10-channel InP-based Arrayed-Waveguide Grating (dimensions = 5.0x6.0 mm) with a 20-GHz channel spacing. The excess loss of the AWG is 5.5-6.3 dB, and the crosstalk level is below -15 dB. Introduction Arrayed waveguide Gratings (AWGs) are one of the key components for wavelength division multiplexing (WDM) applications, and narrowchannel-spacing AWG multi/demultiplexers are indi...
متن کاملDevelopment of a SiGe Arrayed Waveguide Grating in the 2185-2285 cm range
In this paper, we present the design, process and characterization of an AWG based on a SiGe step index waveguide platform, operating at 4.5 μm (2185-2285 cm). A transmission of -1.6 dB and a crosstalk below -12 dB are demonstrated. Keywords— AWG, silicon photonics, multiplexer, gas sensing,
متن کاملAll-Optical Signal Processing and Routing with Spectral Control by a High- Resolution Arrayed-Waveguide Grating
We proposed and designed novel arrayed-waveguide gratings (AWGs) for time-to-space (T-S) conversion-based high-speed optical signal processing. Recently, the frequency selectivity of AWGs has been considerably improved, offering the possibility of powerful tool for the manipulation of optical spectra. An arrayed-waveguide grating was fabricated, integrated with a 90 degree deflecting mirror. Mo...
