In this paper, we experimentally demonstrate an add-drop filter based on wavelengthdependent light coupling between a lithium-niobate (LN) microwaveguide chip and a microfiber knot ring (MKR). The MKR was fabricated from a standard single-mode fiber, and the LN microwaveguide chip works as a robust substrate to support the MKR. The guided light can be transmitted through add and drop functional...
We have demonstrated the Šolc-type wavelength filters in a 52mm long periodically poled Ti diffused lithium niobate channel waveguide which has a domain period of 16.6μm. At room temperature, the center wavelength and the full-width at half maximum of the filter were about 1272.49nm and 0.23nm, respectively. The nearest side-lobe is about 7dB. New structure of optical add/drop multiplexer (OADM...
In this paper, we report our experimental study on directly coupling a micro/nano fiber (MNOF) ring with a side-polished fiber(SPF). As a result of the study, the behavior of an add-drop filter was observed. The demonstrated add-drop filter explored the wavelength dependence of light coupling between a MNOF ring and a SPF. The characteristics of the filter and its performance dependence on the ...
Abstract Free-spectral-range (FSR)-free optical filters have always been a critical challenge for photonic integrated circuits. A high-performance FSR-free filter is highly desired communication, spectroscopy, and sensing applications. Despite significant progress in filters, the with tunable narrow-band, high out-of-band rejection, large fabrication tolerance has rarely demonstrated. In this p...
