Single-mode fiber-optical valve (insulator) consists of round core with outer screw threading with constant pitch p and radius R with ratio, to slots of which in free way (with spare) minimum one turn of one-mode optical fiber is laid, with protective coating, fixed without pressing and bending at ends at output of which polarizer is placed, with axis of polarization directed in parallel to unusual optical axis of bended fiber deflected from line that connects in cross section centers of round core and fiber by angle 16,7° to direction opposite to direction of fiber winding. |
