Cascadable excitability in microrings.
To emulate a spiking neuron, a photonic component needs to be excitable. In this paper, we theoretically simulate and experimentally demonstrate cascadable excitability near a self-pulsation regime in high-Q-factor silicon-on-insulator microrings. For the theoretical study we use Coupled Mode Theory. While neglecting the fast energy and phase dynamics of the cavity light, we can still preserve ...
متن کاملReconfigurable and Cascadable Analog Neuroprocessor
Artificial neural network paradigms have shown the capabilities of performing input-output mapping operations even where the transformation rules are not formally defined, are partially known, or are ill-defined. For high speed processing of such information, hardware implementation sarerequired. At the Jet propulsion Laboratory (JPL), reconfigurable and cascadable building block chips have bee...
متن کاملA Cascadable Vlsi Design for Genet
Constraint Satisfaction Problems (CSPs) are at the heart of many AI applications. The currently existing constraint programming languages and systems are mostly based on heuristic search techniques. The major problems of these techniques are the limited parallelism available in the algorithms and the inadequacy of handling over-constrained CSPs. GENET is a competitive neural network model devel...
متن کاملSlow - Light Dispersion in Periodically Patterned Silicon Microrings
We demonstrate evanescent coupling between a strip waveguide and a periodically-patterned ring resonator in the slow light regime. Resonances with a group index > 22 are efficiently coupled with an extinction ratio of > 20 dB. This result opens up the possibility of new applications in compact device integration in wavelengthdivision multiplexing (WDM) systems while reducing the in-band four-wa...
متن کاملBiochemical sensors based on polymer microrings with sharp asymmetrical resonance
Photonic microresonators have great potential in the application of highly sensitive sensors due to high Q-factor resonances and steep slopes between zero and unity transmission. A microring resonator with increased resonance slopes is proposed by introducing two partially reflecting elements implemented by waveguide offsets. This configuration produces a Fano-resonant line shape and can greatl...
