DESIGN OF ARRAYED WAVEGUIDE GRATING AWG DEMULTIPLEXER BASED

Based on grating waveguide arrays

Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. It is usually built as part of a planar lightwave circuit (photonic integrated circuit), where the light coming from an input fiber first enters a multimode. Component-level simulations using varFDTD are carried out for more realistic results. It is a very powerful integrated light-dispersion technology with sig-nificant exibility for tailoring its performance to the individual.

Comparison of Low Loss and Performance of Arrayed Waveguide Gratings

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.

Lithium Niobate Array Waveguide Grating

We design and fabricate an eight-channel thin-film lithium niobate (TFLN) arrayed-waveguide grating (AWG) and demonstrate the electro-optical tunability of the device. The transmission of the fabri-cated TFLN AWG near the central wavelength of 1550 nm is. Arrayed waveguide grating is a versatile and scalable integrated light dispersion device, which has been widely adopted in various applications, including, optical communications and optical sensing.

Identical Low-Reflection Fiber Bragg Grating

Fiber Bragg gratings (FBGs) present a way to realize narrow-band reflectors directly in the fiber. They consist of thousands of strip-shaped refraction index changes in the core of the fiber, perpendicular to its axis. Serious signal crosstalk occurring between large-serial of identical FBGs, however, has limited the further increase in the. Bragg gratings are crucial components in passive photonic signal processing, with wide-ranging applications including biosensing, pulse compression, photonic computing, and addressing. In the vast realm of optical fiber sensing, where precision and innovation converge, Fiber Bragg Gratings (FBGs) stand as luminaries, casting their influence across myriad applications. High demands are placed on optical components for industrial fiber lasers in the kilowatt range: they must be able to withstand a high temperature and photon density, have low losses, be insensitive to vibration and other environmental influences.
