文摘

Twin-core fiber optical tweezers (TCFOT) can be simulated using finite difference beam propagation method. We chose a tapered TCFOT and calculated its far-field pattern. It is found that, there is an optimum for the core index to have maximum peak at far-field pattern of a tapered TCFOT. This optimum value, can achieved a maximum force on the particles trapped at the far-field region of tapered TCFOT.
