Abstract
An optical apparatus and method for selectively transmitting optical signals utilizes an optical component having a controllable optical state to selectively manipulate the optical signals so that transmission of the optical signals through the optical apparatus is controlled. The optical apparatus is configured so that optical signals from a first port of the optical apparatus are transmitted to a second port of the optical apparatus regardless of the optical state of the optical component. The optical apparatus is further configured so that optical signals from the second port are not transmitted to the first port unless the optical component is switched to an active optical state.
