ABSTRACT:
A system and method for providing an optical isolator comprising a first collimating means, a core, and a second collimating means is disclosed. The first collimating means comprises at least a first optical fiber holder, a first lens, and a first collimator holder. The core comprises a first polarizer, a polarization rotation means, and a second polarizer. The second collimating means comprises at least a second optical fiber holder, a second lens, and a second collimator holder. One aspect of the method and system provides a quartz collimator aligner in a collimating means. The quartz collimator aligner aligns the optical fiber holder and the lens. The collimator holder is disposed around the quartz collimating aligner. The quartz collimator aligners improve the alignment of the collimator, thereby reducing insertion loss. The smoothness quartz collimator aligners also increases return loss. Another aspect of the method and system provides a core assembly holder in which the polarization rotation means is disposed. This embodiment increases the ability to adjust the orientation of the first and second polarizers.
