Femtosecond optical tweezers are an effective tool for handling individual human red blood cells, as they allow for comparatively easy single cell manipulation with consequent diverse applications in biological science. Optical trapping at low power with short exposure time is desired in order to minimize damage in the vicinity of targeted tissue, and such a requirement can be achieved by using micro-ring resonators in an optical tweezers configuration. This paper describes a modified add/drop multiplexer system, known as half-panda ring resonator, which is suitable for human blood cells trapping and deployment during investigations on deformation and vibration behavior of biological cells. Dark-bright solitons and Gaussian beams are propagated within the proposed system, while the output features can be controlled via manipulation of specific parameters. This study details optical tweezers of FWHM of 33 and 100, and 90 and 152 femtoseconds that are generated at the drop and through ports of the system respectively
