We propose and demonstrate an all-fiber high Q Mach-Zehnder interferometer (MZI)-coupled microknot resonator (MZKR) structure using optical microfibers drawn from silica fibers The experimental results show that this microfiber-based structure achieved a high Q factor of similar to 15,000 and good interference fringes with extinction ratio of up to similar to 15 dB By optimizing the loop-length of the microfiber knot and the optical path-difference of the MZI, the desired MZKR with higher Q factor and better extinction ratio could be obtained A series of integrated all-fiber optical devices could be realized based on such a MZKR structure due to its outstanding advantages of easy fabrication, great flexibility, low cost. low loss. etc.
