Silicon Based Arrayed Waveguide-
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. These design of these devices are based on an.

Applications in planar optical waveguide chips
Planar waveguides play a crucial role in enabling high-speed data transfer in optical interconnects. Ultra-low loss optical planar waveguide technology is a critical research area driven by the need to improve energy effi-ciency and advance the power handling capability, performance, function and complexity of photonic integrated circuits and systems-on-chip. They are typically fabricated as thin films with a higher refractive index than the surrounding materials. This configuration allows the waveguide to confine light within the film. An all-optical plasmonic sensor platform designed for smartphones based on planar-optical waveguide structures integrated in a polymer chip is reported for the first time.

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.
