Abstract: Highly-efficient, fabric-wide calibration of balanced control for optical switch fabrics without built-in power-detectors is first realized with fully-automated implementation. This technique co-optimizes thermo-optic and electro-optic phase elements, correcting phase-error and power-imbalance simultaneously for optimized performance.

This paper presents mechanical behavior of a functionally graded (FG) cantilever micro-beam subjected to a nonlinear electrostatic pressure and thermal moment considering effects of material length scale parameters. Material properties through the beam thickness direction are graded. The top surface of the micro-beam is made of pure metal and the bottom surface from a mixture of metal and ceram...

The relative sliding motion of two elastic bodies in contact induces wear process and contact shape evolution. The transient process tends to a steady state occuring at fixed contact stress and strain distribution. This state corresponds to the minimum of the wear dissipation power. The optimality conditions of the functional provide the contact stress distribution and the wear rate compatible ...

The effect of a sacrificial layer residue on a cantilever beam in the nano-electro-mechanical nonvolatile memory is investigated for the optimization of reliability characteristics. Different from previous research, pull in voltage model of nano-electro-mechanical nonvolatile memory used triangular residue layer which is considered by real wet etching process. Modified pull in voltage model was...
