Fabrication and characterization of machined multi-core fiber tweezers for single cell manipulation

We have found an error in our work reported in [Opt. Express26(3), 3557 (2018)], which we correct in this erratum. We used incorrect data for the experimentally measured values of power of the fibre trap and power of the conventional optical tweezers (OT) used to 'break' the fibre trap. Using the correct data, Ffibre and Q (force and quality) of the multicore fibre tweezer are re-calculated. In this erratum, we communicate the correct values of Ffibre and Q and publish a revised Fig. 7 that contains results based on the correct data. Based on the revised result, two statements, in the abstract and conclusions, are also revised. The fabrication method, technique and general conclusion remain unaffected.
