Analysis of laser power threshold for self oscillation in thermo-optically excited doubly supported MEMS beams
An optically thin MEMS beam suspended above a substrate and illuminated with a CW laser forms an interferometer, coupling out-of-plane deflection of the beam to absorption within it. In turn, laser absorption creates thermal stresses which drive further deflection. This coupling of motion to thermal stresses can cause limit cycle oscillations in which the beam vibrates in the absence of periodi...
متن کاملSpontaneously excited pulses in an optically driven semiconductor laser.
In optically injected semiconductor lasers, intrinsic quantum noise alone, namely, the spontaneous emission and the shot noise, are capable of exciting intensity multipulses from a steady state operation. Noisy lasers exhibit self-pulsations in the locking region of the corresponding deterministic system. The interpulse time statistics are studied in parameter regions near k-homoclinic (Shilnik...
متن کاملFlow-driven Interactions for Adaptive Pervasive Applications
The era of ubiquitous and pervasive computing technology opens the world for new pervasive applications and services within the physical surroundings. Often users find themselves dealing and interacting with multiple applications simultaneously to achieve certain goals to satisfy certain motive. Currently, pervasive computing applications are individually created and tailored with little or no ...
متن کاملAdaptive, Model-driven Autoscaling for Cloud Applications
Applications with a dynamic workload demand need access to a flexible infrastructure to meet performance guarantees and minimize resource costs. While cloud computing provides the elasticity to scale the infrastructure on demand, cloud service providers lack control and visibility of user space applications, making it difficult to accurately scale the underlying infrastructure. Thus, the burden...
