  • Use of Waveguide Array Gratings

    Use of Waveguide Array Gratings

    Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These design of these devices are based on an. 990) and Dragone (1991). 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. 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 compare the effect of output waveguide configurations on the performance of AWGs. The operation principle of the AWG is described and additionally some simple design rules are given.


  • What is a Georgian fiber optic grating

    What is a Georgian fiber optic grating

    A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. Hence a fiber Bragg grating can be used as an inline optical filter to bloc. HistoryThe first in-fiber Bragg grating was demonstrated by in 1978. Initially, the gratings were fabricated using a visible laser propagating along the fiber core. In 1989, Gerald Meltz and colleagues demonstrat. The fundamental principle behind the operation of an FBG is, where light traveling between media of different refractive indices may both and at the interface. The refracti. The term type in this context refers to the underlying mechanism by which grating fringes are produced in the fiber. The different methods of creating these fringes have a significant effect on physical att.
