... consumption in silicon microring modulators was demonstrated to be as low as 85 fJ/bit [1]. Such low power devices are enabled by narrow bandwidth, high Q resonances. Due to the high thermo-optic coefficient of silicon and the wide variation in temperatures at the core of micro-processors thermal co ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
