    High-precision arrayed waveguide gratings used in the Finnish subway

    We have developed our first generation of AWG devices using a silica-on-silicon substrate with a very thin layer of Si3N4 in the core of our waveguides. They image the field in an input waveguide onto an array of output waveguides in such a way that the different wavelength signals present in the input waveguide are imaged onto different output waveguides. These devices are capable of multiplexing many wavelengths into a single optical fiber, thereby increasing the transmission capacity of optical networks considerably. 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. A comprehensive design of a folded-architecture arrayed-waveguide-grating (AWG)-device, targeted at applications as integrated photonic spectrographs (IPS) in near-infrared astronomy, is presented.

  • Optical Coupler Waveguide Type

    Optical Coupler Waveguide Type

    A waveguide type optical coupler includes a Mach-Zehnder interferometer that includes two arm waveguides between two directional couplers. Couplers of this type are usually called directional couplers because the energy is transferred in a coherent fashion so that the di ection of propa-gation is maintained. Directional couplers have been fabricated in two basic geome-tries: multilayer planar. Coupled mode analysis has been the most widely used method to study such coupling in which the interaction leads to transfer of power from one waveguide to the other or between modes of the same waveguide due to index perturbations. This guide will explain their fundamental principles, various types, and significant applications within modern communication technologies.
