Entrainment of Micromechanical Limit Cycle Oscillators in the Presence of Frequency Instability
Limit cycles micromechanical devices optical resonators oscillators thermomechanical processes
2015/8/27
The nonlinear dynamics of micromechanical oscil-lators are explored experimentally. Devices consist of singly and doubly supported Si beams, 200nm thick and 35 μm long.When illuminated within a laser ...
Real-time Detection of a 40 Gbps Intradyne Channel in the Presence of Multiple Received WDM Channels
Fiber optics communications Networks Coherent communications
2015/6/5
We characterize a single-ended intradyne receiver’s performance when multiple channels are received without optical demultiplexing. A 40Gb/s dual-polarization QPSK channel is recovered from 16 interfe...
DGD Estimation from FIR Filter Taps in Presence of Higher Order PMD
DGD Estimation FIR Filter Taps Higher Order PMD
2015/7/31
We estimate the DGD τ ( ω ) over the complete system bandwidth from FIR filter taps in coherent receivers with digital equalization, obtaining accurate DGD values even in presence of higher order PMD...
Temporal Coupled-Mode Theory and the Presence of Non-Orthogonal Modes in Lossless Multimode Cavities
Electromagnetic coupling fi lters optical switches resonance
2015/8/11
We develop a general temporal coupled-mode theory for multimode optical resonators. This theory incorporates a formal description of a direct transmission pathway, and is therefore capable of describi...
