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.
In this paper a second-Order low distortion Sigma-Delta Modulator (SDM) with utilization of comparator-based switched-capacitor (CBSC)-based IIR filter, is explored. The advantages of this new structure are justified by the reductions of power and area. For this purpose IIR filter block can be made with single CBSC gain stage that has the same accuracy and performance of 2nd-order filter with two...
Far field distribution of twin-core fiber optical tweezers (TCFOT) is calculated using FDTD-BPM method. It is found that there is an optimum for core index to have maximum peak at far-field of a tapered TCFOT.
Twine core optical tweezers are studied and simulated in this work. We found that it is possible to have better action of these structures using a proper dimension of the fiber cores at tip.
