Abstract

Optical nonreciprocal devices, i.e. isolators and circulators, are some of the most important elements in future fiber transmission systems. Today optical communication is realized with extremely high data rates up to some Gbit/s. Therefore a stabilized transmitter is required, in our case a semiconductor laser diode with a linewidth below some hundred kHz. Especially in coherent optical systems the laser has to be protected from undesired reflections caused by splices, couplers or other perturbations. This is the task of an optical isolator. On the other hand an optical circulator will open new aspects in future optical fiber communication, e.g. two way communication or for the application in OTDR's.
