研究目的
To present an innovative method for additive manufacturing of optical multimode waveguides for short range data transmission using aerosol jet printing, comparing it to other manufacturing techniques.
研究成果
The aerosol jet printing technique offers a promising, innovative approach for manufacturing long, flexible, and cost-effective polymer optical waveguides suitable for high-speed data transmission up to 10 Gbit/s. Despite its advantages in length and 3D-ability, improvements in optical performance, miniaturization, and environmental stability are needed to compete with traditional methods.
研究不足
The aerosol jet printing process currently faces challenges in controlling environmental conditions within the machine, leading to process stability issues. The technique is also limited to multimode waveguides due to nozzle clogging risks with smaller sizes.
1：Experimental Design and Method Selection:
The study employs aerosol jet printing for manufacturing polymer optical waveguides (POW) on flexible substrates, comparing it with other techniques like photolithography, imprinting, dispensing, and ion-exchange.
2：Sample Selection and Data Sources:
Uses a 175 μm thick PMMA-foil substrate conditioned with silicone containing varnish for waveguide fabrication.
3：List of Experimental Equipment and Materials:
Includes an aerosol jet printing unit, PMMA-foil substrate, ACTEGA G8/372L varnish, J+S 390119 core material, and various measurement tools like spectrophotometer, laser scanning microscope, and shear force measurement device.
4：Experimental Procedures and Operational Workflow:
Describes the two-step printing process involving conditioning line printing and core material printing, followed by UV-curing and optical characterization.
5：Data Analysis Methods:
Analyzes mechanical (shear strength) and optical performance (transmittance, near field, attenuation) of the waveguides, including data transmission performance up to 10 Gbit/s.
