Abstract
A system and method of utilizing spherical and hemispherical shaped devices to function as an optical switch is disclosed. The optical switch can contain mirrors that turn on and off, or are fixed in place with a movable spherical device. Additionally, the optical switches can contain grating patterns to deflect an optical signal from its original path. The grating patterns can vary in design and pattern to deflect the optical signal in almost any direction, or to not let the optical signal continue. The optical switch can also include photo sensors along the exterior of the sphere or along the reflection device. The optical switch can also include an integrated circuits.
