Abstract :
A real non-contact two-core single fiber optical tweezers is proposed. It is fabricated by the fiber grinding and polishing technology. The yeast cells trapping performance realized by this single fiber optical tweezers with a special designed truncated cone tip fiber probe is demonstrated and investigated. The distribution of the output optical field emerging from the truncated cone fiber tip is simulated by using the FDTD (finite domain time difference) method. The axial and transverse optical trapping forces are also simulated with the FDTD method. This new single fiber optical tweezers can realize truly non-contact remote optical trapping of micro particles and provides a new application for the biological and medical researching fields.
