Optical fiber systems for transmitting laser light with reduced back reflection interference

---

Abstract

---

In accordance with the invention, an optical fiber system comprising a laser source an optical fiber including a reflective input end for receiving light from the source is provided with a polarization quarter-wave plate between the laser and the reflective end for minimizing power fluctuations from back reflection. The quarter-wave plate does not prevent back reflection but rather rotates the polarization of the back reflected light so that it does not interfere with the polarized light within the cavity. In an advantageous embodiment the quarter-wave plate is disposed within a receptacle laser package.
