Paper Abstract

Recently, novel resonator assembled from the microfiber, so-called the optical microfiber knot resonator (MKR) has attracted lots of interests. In this paper, we review our studies on slow light in MKRs with several kinds of structures. Firstly, based on analyzing the relationship between the output field and the input one, we give the theoretical descriptions of the light propagations in the MKR, in the microfiber multi-knot resonator with a parallel structure, and in the microfiber multi-knot resonator with a serial structure, respectively, together with the slow-light performance of them. Secondly, we theoretically analyze and experimentally investigate how to design and fabricate a tapered microfiber with good optical and mechanical performance. Thirdly, we introduce our approach to fabricating the MKRs with different structures employing the assistance of the polymer microfiber. Finally, we demonstrate a wide-bandwidth and zerodispersion slow light in the microfiber double-knot resonator with a parallel structure based on an analogue of EIT through changing the correlated parameters, such as the coupling coefficients, and the diameters of the two knot rings.
