Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional photonic signal modulators are used, then photonic computing and communication devices can be constructed, but resonance interaction between photonic elements cannot be effectively reduced or eliminated, limiting performance and efficiency
Solution Approach 1:
The patent applies parameter changes by controlling the phase alignment of carbon nanotubes through external fields (electromagnetic or mechanical). By adjusting the phase parameter of the nanotube array, the resonance interaction between photonic elements can be dynamically reduced or eliminated, thereby improving device performance and efficiency without sacrificing the photonic computing functionality
Solution Approach 2:
The patent introduces carbon nanotubes as an intermediary element between photonic components. These nanotubes act as a mediating layer that can be controlled to modify the resonance interaction between photonic elements, enabling dynamic control over signal modulation while reducing harmful resonance effects through phase alignment adjustments
2Use of energy by moving object
If carbon nanotubes are aligned to produce resonance interaction, then antenna-like response to incident light is achieved, but the resonance interaction cannot be dynamically controlled for signal modulation
Solution Approach 1:
The patent transforms the static resonance interaction into a dynamic controllable parameter. By applying external electromagnetic or mechanical fields to the carbon nanotube array, the phase alignment and consequently the resonance interaction can be dynamically adjusted in real-time, enabling the system to adapt between enhancing and reducing resonance effects as needed for different signal modulation requirements
Solution Approach 2:
The carbon nanotube array serves multiple functions: it maintains antenna-like response for light absorption and emission while simultaneously providing dynamic control over resonance interaction. This multi-functionality allows the same structure to both generate useful antenna effects and control harmful resonance, depending on the applied phase alignment

AI summary
The present invention contemplates a variety of methods and techniques for fabricating a carbon nanotube (CNT) signal modulator for reducing, eliminating, or enhancing the resonance interaction between photonic elements, and a photonic transmission device that may incorporate the signal modulator. The CNT signal modulator comprises a gate CNT on a substrate in a position for receiving an input photonic signal and an input modulation signal; and transmitting an output photonic signal that is reduced, eliminated, or enhanced through the selection of the input modulation signal; and an input modulation signal sender for sending the input modulation signal to the gate CNT and creating the modulated output photonic signal from the gate CNT. The photonic transmission device can contain a plurality of CNTs, each having functional antenna forms that are capable of a resonance interaction of photons between adjacent CNTs when formed as an array on a substrate. The photonic transmission device can also comprise the CNT signal modulator.
