Rocking filter induced mechanically in a highly birefringent microstructured polymer fiber.

We present the possibility of mechanical inducement of a rocking filter in a birefringent microstructured polymer fiber, which resonantly couples polarization modes. A birefringence in the fiber used for rocking filter fabrication is induced by two large holes adjacent to the core. Because of the small pitch distance of the microstructured cladding, the… (More)
