Semiconductor Optical Amplifier (SOA)-Fiber Ring Laser and Its Application to Stress Sensing
Fiber Laser Fiber Sensor Ring Laser Semiconductor Optical Amplifier Optical Sensor
2013/1/30
We have developed a novel optical fiber ring laser using a semiconductor optical amplifier (SOA) as the gain medium, and taking advantage of polarization anisotropy of its gain. The frequency differen...
Numerical study on thermal stress cutting of silicon wafer using two-point pulsed laser
brittle materials thermal stress laser cutting
2011/5/5
Laser cutting using the controlled fracture technique has great potential to be used for the separation
of brittle materials. In this technique, thermal stress is used to induce the crack and the mat...
Dynamic Birefringence Induced Extensional Stress in Curled Hole-Assisted Fiber
Fiber measurements Birefringence
2015/6/10
This paper describes the dynamic birefringence induced by the extension of a curled optical hole-assisted fiber, which increases linearly under high tension. This technique can be a used for monitorin...
Laser-induced stress waves facilitate targeted gene transfer（图）
Laser-induced stress waves targeted gene cells tissues
2009/6/17
It is well established that a strong pressure wave, known as a photomechanical or laser-induced stress wave (LISW), accompanies laser-induced plasma. For medical applications, LISWs are often undesira...
Stress Induced Effects for Advanced Polarization Control in Silicon Photonics Components
Stress Induced Effects Polarization Control Silicon Photonics Components
2009/5/19
We review the use of the oxide cladding stress-induced photoelastic effect to modify the polarization dependent properties in silicon-on-insulator (SOI) waveguide components, and highlight characteris...
Stress at the initial stage of growth for Lennard–Jones films
film growth stress molecular dynamics simulation
2011/5/11
Molecular dynamics simulation was used to study the influence of a relative size of adsorbed and substrate atoms on the stress of growing films. Atoms in the system interact via the Lennard–Jones pote...

Measurement of stress as a function of temperature in Ag and Cu thin films
annealing stress measurements thin films
2011/4/27
Stress measurements of 23 nm copper films and 93 nm silver films on Si (100) have been performed during thermal cycling between RT and 450°C. The changes in stress versus temperature are interpreted. ...
Post-deposition stress evolution in Cu and Ag thin films
stress curvature measurements thin film
2011/4/27
Evolution of stresses in thin Cu and Ag films after deposition by thermal evaporation in UHV system is studied. Thin films were deposited on 100 mm thick Si substrate at room temperature. Deposition r...
