POLARIZATION-MAINTAINING FIBER ARRAY BLOCK AND METHOD FOR PRODUCING SAME, AND INTEGRATED OPTICAL DEVICE USING POLARIZATION-MAINTAINING FIBER ARRAY BLOCK

摘要

Disclosed is an optical fiber array block in which a polarization-maintaining fiber array is inserted. A polarization-maintaining fiber array block according to one embodiment of the present technology comprises at least one groove which is etched such that polarization-maintaining fibers can be inserted therein, wherein the groove has a cross section which may be in the shape of a rhombus.
