Manufacturing Integrated Optical Data Buses

Optical Loss. Optical loss is another key property for any EOI. There are intrinsic and extrinsic sources of optical loss for any waveguide material. Intrinsic losses occur from the material itself due to absorption. Absorption losses arise from vibrational overtones of the aliphatic and hydroxyl groups present in the material. Absorption effects in general are more prominent at the higher wavelengths, with hydroxyl groups having an especially strong effect at the 1550nm wavelengths.
