Abstract We report broadband RF channelizers based on integrated optical frequency Kerr micro-combs combined with passive micro-ring resonator filters, with microcombs having channel spacings of 200GHz and 49GHz. This approach to realizing RF channelizers offers reduced complexity, size, and potential cost for a wide range of applications to microwave signal detection.

Highly Sensitive Detection

Here we report on fabrication of integrated-optical sensors for relative humidity and ammonia detection based on natural polysaccharide chitosan. The sensing properties of the fabricated sensor to gaseous ammonia are presented. The sensor exhibits a linear response in the range of 1-300 ppm with the response time less than 1 second. It has been shown that 1 μm-thick chitosan-based waveguide film allows highly sensitive detection of RH level.

Plasmon Induced Transparency

We demonstrate the realization of plasmon induced transparency (PIT) in a nanostructure composed of silver nanobars and a silver nanodisk. The optical properties of the planar metamaterials have been investigated theoretically in the paper. The classical coupled harmonic oscillator model demonstrates the PIT phenomenon in a nanodisk–nanobar system. Additionally, double PIT response is observed when two nanobars are located in proximity to the silver nanodisk. The PIT window wavelength and bandwidths can be efficiently tuned by controlling the geometric parameters such as the lengths of nanobars and the coupling distances between the nanodisk and nanobars. Moreover, the transparency window shows highly sensitive response to the refractive index of the environmental medium. A high figure of merit up to 15.5 of the asymmetrical system for refractive index sensing is achieved. The tunability of the PIT may have potential application on slow light and highly integrated optical circuits.
