Optical Microfiber Knot Resonators: Fabrication and Transmission Properties
نویسنده
چکیده
In this paper, an MKR has been fabricated from an unbroken double-ended tapered microfiber. Since the guided light can be transmitted in and out of the resonator directly by integral full-size fiber ports, the proposed device has much lower insertion loss, and is more stable and robust in structure. The Q-factors of resonance exceeding 40000 are achieved at the optical communication wavelengths of 1550nm. In addition, the optical transmission properties of the fabricated MKRs have been theoretically and experimentally demonstrated.

متن کاملHighly sensitive refractive index sensor based on cascaded microfiber knots with Vernier effect.
We propose and experimentally demonstrate a refractive index (RI) sensor based on cascaded microfiber knot resonators (CMKRs) with Vernier effect. Deriving from high proportional evanescent field of microfiber and spectrum magnification function of Vernier effect, the RI sensor shows high sensitivity as well as high detection resolution. By using the method named "Drawing-Knotting-Assembling (D...
