Conical Trap Nanostructure for Compact Spectral Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a compact, small-scale structure capable of efficiently separating, combining, or redirecting multispectral electromagnetic radiation, particularly for applications requiring spatial separation of spectral components by frequency and polarization, and do not effectively integrate such functionality with transducers in a stratum.
Innovation Solution
A tapered cavity structure, referred to as a Conical Trap (CT), is embedded within a substrate, allowing for the spatial separation or combination of spectral components by frequency and polarization, and can operate in splitter, combiner, or reflective modes, with transducers disposed to receive or reflect the separated components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional refraction methods are used to separate spectral components, then spatial separation by frequency is achieved, but the device complexity and scale increase significantly
Solution Approach 1:
The device segments the spectral separation function into multiple discrete conical traps, each tuned to specific frequency ranges. This allows complex spectral manipulation to be achieved through simple, repeating unit structures rather than a single complex refractive element.
Solution Approach 2:
The patent transitions from conventional 2D planar refraction to 3D vertical stacking of conical traps. Spectral separation is achieved in the vertical dimension through resonant frequency tuning of stacked traps, enabling compact spectral manipulation without large horizontal footprints.
2Measurement precision
If conventional spectral separation devices are used, then spectral components are separated, but the device size becomes large and not compact
Solution Approach 1:
Multiple conical traps are nested vertically in a stacked configuration, with each trap containing resonant structures that exploit the vertical dimension. This nesting allows multiple spectral functions to be packed into a compact vertical space, dramatically reducing device volume while maintaining separation precision.
Solution Approach 2:
The patent changes the operating parameter from conventional refractive index manipulation to resonant frequency tuning. By adjusting the resonant frequencies of stacked conical traps, precise spectral separation is achieved in a compact volume, avoiding the large-scale refractive optics required by traditional methods.
3Measurement precision
If conventional refraction is used for spectral manipulation, then spectral separation is achieved, but integration with transducers in a stratum is not effective
Solution Approach 1:
The conical trap structure serves multiple functions simultaneously: it acts as a spectral separator through resonant frequency tuning, provides a compact vertical platform for transducer integration, and enables both transmission and reflection modes. This multi-functionality allows effective integration with transducers in a stratum configuration.
Solution Approach 2:
The stacked conical traps serve as an intermediary structure between incident electromagnetic radiation and transducers in the stratum. The traps resonate at specific frequencies to couple energy efficiently to transducers positioned at different vertical levels, enabling effective spectral-to-spatial energy transfer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The CT structure efficiently separates or combines multispectral electromagnetic radiation, enabling the spatial separation of spectral components and their redirection, while integrating with transducers for energy conversion, thus addressing the need for compact spectral manipulation in various applications.
Implementation Method 1
In its most basic form, the term 'refraction' means the change of direction of a ray of light, sound, heat, radio waves, and other forms of radiant energy, as it passes from one medium to another. Generally waves of different frequencies would refract at different angles and different speeds in different mediums, and thus refraction tends to spatially separate multispectral radiant energy into its spectral components by frequency.
Implementation Method 2
The cavity has a depth direction extending between the first end and the second end, wherein the depth magnitude increases with distance from the first end towards the second end
Implementation Method 3
Various areas will benefit from mixing various spectral components into a broader type of radiant energy, combining a plurality of 'narrower' spectral components into a 'broader' radiant energy
Implementation Method 4
at least a first and a second energy transducers disposed about the CT to receive the spectral components

AI summary
Tapered cavity structures disposed within a stratum may be configured as a spectral component splitters, a spectral component combiners, and various combinations thereof including a reflective mode of operation. The tapered cavities have an aperture at their wider and a tip at the narrower, and are dimensioned such that multi-spectral radiant energy admitted into the cavity via the aperture would depart the tapered cavity via its side periphery at a depth and/or direction dependent on its frequency and/or its polarization, and that a plurality of spectral components admitted to the cavities via the its peripheral side or sides will be mixed and emitted via the aperture. Reflective type structures where portions of radiant energy is selectively absorbed and other portions are reflected are also considered. Differing stratums are disclosed. Applications of the tapered cavities in a stratum are also disclosed.
