This work describes a laser based technique to adjust curvatures of silicon microcantilevers used for chemical and biological detection. In batch fabricated silicon cantilever arrays used for parallel sensing, it is often desirable that all cantilevers have nearly identical curvatures or flatness. We demonstrate that using the laser technique, it is possible to adjust curvatures by an amount as...
Mechanisms of the process are examined to better understand the deformation characteristics such as slightly protruded shape at the intrados, wall thickness variation, cross-section ovalization, bending radius, and asymmetry. A finite element model is developed and validated by experimental observations. Factors important to characteristics of deformation are experimentally and numerically inve...
Numerical simulation analysis of fiber optic bending sensitivity aiming to improve fiber lasers design is developed, analyzing both the transition loss, associated with abrupt curvature change at the beginning and the end of a bend, and pure bending loss associated with the loss from the constant curvature bending in between.

A non-contact method for the observation of the elastic deformation of 2D molybdenum disulfide (MoS2) thin films using an ordinary optical microscope is reported. A pulsed laser is used to rapidly increase the bending deformation of the MoS2 thin films via heating. The bending angle of the MoS2 thin films shows high stability, changing only 5% in forty days without external forces. However, the...
