MATH In such settings, depending on the optical properties of the polymer, the propagation losses might then become dominated by the absorption and scattering in the polymer and not by the silicon gratings. In all applications, waveguides are used to "guide" electromagnetic waves in specific directions, shapes, or patterns. A Waveguide acts like a high pass filter due to this characteristics. These new applications focus particularly on the UV to Near IR (NIR) range (200 nm-900 nm). Furthermore, the application-specific spectral range imposes restrictions on the possible material set and technology;7 for example, the common silicon photonics platform is not usable for visible light. To assess the propagation loss, we realize waveguides of different lengths between 2 and 8mm. Express 20, 1088810895 (2012). Optical Waveguides, Devices and Applications. 3). They also exist in the form of wires, coaxial cables, parallel plates, or optical fibers. A waveguide is a device that transmits these waves from one place to another, so as the name suggests, an optical waveguide is a medium device that guides the propagation of light waves through it. Abstract One-dimensional organic structures with well-oriented -aggregation, strong emission, and ease of processability are desirable for optoelectronic waveguiding devices. More quantitatively, from the simulated overlap and the silicon absorption of ~3880cm1 at =600nm, we expect ~6.7dB/cm of the waveguide loss to be attributed to the material absorption in the silicon elements, whereas any excess loss is most likely related to lateral leakage, scattering or absorption in other materials.
