This information pertains to defining different types of optical circuitry boards. These boards would likely be produced using optical / opaque semi-conductor materials. The materials may vary depending on the type of optical circuitry, the type of optical circuit board, the use / application of the optical circuit board, and the scale of the circuitry such as regular, micro, nano, and/or pico. There may be optical circuitry boards that have multiple types and multiple sizes of optical circuitry.
