Fabrication and Characterization of a 2 × 2 Microfiber Knot Resonator Coupler

A 2 × 2 microfiber knot resonator (MKR) coupler is demonstrated. The hybrid device is obtained by forming a knot within the coupling region of a microfiber coupler with a 50:50 splitting ratio. The microfiber coupler is successfully fabricated by laterally fusing and tapering two optical fibers usin...
