Direct laser writing (DLW) is a powerful tool toward the development of ultimate three-dimensional (3D) photonic devices. Because of the increasing demand for realising nano-geometries, the diffraction-limited resolution associated with DLW should be overcome to access the nanoscale. To meet this challenge, the concept of 3D nano printing, which is called super-resolution photoinduction-inhibition...
This paper proposes a one-body optical torque sensor. The proposed sensor has advantages of anti-slip and low cost due to the simple one-body structure. Simulations for stress and strains analysis are accurately performed. To demonstrate the performance of proposed design, experiments were also carried out to compare it with a commercial force/torque sensor (Mini45, ATI).
Quantum rods (QRs) are incorporated into polymers that are doped with azo dyes via an energy transfer process. The polarization-dependent refractive-index change allows four-dimensional optical data storage as well as other polarization-controlled photonic applications.
We present the concept of a refractive index sensor based on integration of a three dimensional photonic crystal with a microchannel by femtosecond laser fabrication. The sensor performance was characterized by FTIR spectroscopy.
