Abstract: A compact, in-line polarization combiner uses a folded, reflective optical path from a first fiber to a second fiber. The combiner includes first and second fibers at one end of an in-line package, and a third fiber at the other end of the in-line package. A first polarization-dependent optical path is defined between the first and second fibers for light in a first polarization state. A second polarization-dependent path is defined between the first and third fibers for light in a second polarization state orthogonal to the first polarization state. A polarizer is disposed between the ends of the combiner and reflects light on the first path between the first and second fibers and transmits light on the second path between the first and third ports, A reflector is disposed on the first path to reflect light to the polarizer.

Abstract: A bit error rate or other performance characteristic of a communication link is monitored using a state machine. The state machine includes at least three states — for example, a NO ALARM state, an ALARM DETECTION state, and an ALARM state. A sliding window is used to determine when to transition from the ALARM DETECTION state to the NO ALARM state or the ALARM state. A sliding window is also used to determine when to transition from an ALARM state to a NO ALARM state. A respective sum is calculated as a function of the sliding window for use in making such determinations.

Abstract: An apparatus for locking the wavelength of a laser uses a non-planar etalon, for example a non-parallel etalon, to produce a periodic spatial interference pattern, typically in the light reflected from the etalon. The apparatus also uses a detector to detect the spatial interference pattern having at least three separate detector elements, commonly referred to as pixels. The etalon and the detector are matched to each other so that adjacent pixels detect a specific portion of the phase of the periodic interference pattern.
