Summary
Miniaturization in nanophotonics shows performance limits. Device scaling laws reveal non-monotonic behavior, impacting optoelectronic device power and speed, especially below 100nm.
Area of Science:
- Optoelectronics
- Nanophotonics
- Materials Science
Background:
- Miniaturization in information technology has driven advances, motivating nanophotonic device development.
- A fundamental understanding of scaling laws for nanophotonic devices is currently lacking.
Purpose of the Study:
- Analyze scaling laws for optoelectronic devices at micro and nanometer scales.
- Investigate the influence of scaling on device performance, power consumption, and operating speed.
Main Methods:
- Analysis of scaling laws for optoelectronic devices.
- Evaluation of four photonic device classes: laser sources, electro-optic modulators, photodetectors, and all-optical switches.
- Study of three optical resonator types: microring, Fabry-Perot cavity, and plasmonic metal nanoparticle.
Main Results:
- Optoelectronic device performance scales non-monotonically with device length due to tradeoffs.
- Microring and Fabry-Perot cavities outperform plasmonic cavities at larger scales.
- These devices cease to function below 100nm due to insufficient optical/electrical functionality.
Conclusions:
- Provides a detailed understanding of nanophotonics limits.
- Establishes a roadmap for optoelectronics, similar to the International Technology Roadmap for Semiconductors.

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...
