Ultra-short bandwidth optical tweezer generation using GaAs ring resonator system

In this article, the modified add/drop multiplexer system as ring resonator is proposed for optical tweezers generation. The entire effect is analyzed by the nonlinear existence of the proposed structure. The manipulation is of major importance and nanometer bandwidth optical tweezers are an effective tool for manipulating individual particles, where these can be applied for many applications in medical science. The trapping size of the tweezers varies depending on the bandwidth of the launching pulses, thus particles with nano and micrometer diameter can be tapped and stored within the system. In this study 10 and 15 nm optical tweezers could be generated at the drop and active ports of the ring resonator. The proposed ring resonator uses the GaAs waveguide to perform the interferences between the input waves which are the dark and bright solitons. © 2019 The Authors
