Abstract
An optical ferrule () includes an input surface () for receiving and transmitting a central light ray () from an optical fiber () attached to the optical ferrule. A light redirecting side () receives, along a first direction (), the central light ray () transmitted by the input surface () and redirects the received light along a different second direction (). The redirected central light ray () exits the optical ferrule through an output surface () of the optical ferrule. As the central light ray () propagates in the optical ferrule from the input surface () to the output surface (), the central light ray () propagates through distinct first and second portions () of the optical ferrule having different respective first and second compositions.
