Broadband coupler

---

Abstract

---

An input light beam is deflected by a totally reflective surface of a corner prism towards another surface of the prism which is coated by a partially reflective coating. A predetermined percentage of the input power is reflected by this coating and the remainder transmitted therethrough. The reflected optical power is collected by an output fiber and the transmitted power is directed towards another coating which either totally or partially reflects such power to another output fiber to accomplish optical coupling.
