Summary
We fabricated micrometer-scale mid-infrared lenses using inkjet printing. These arsenic sulfide spherical microlenses offer tunable focal lengths for integrated optics applications.
Area of Science:
- Optics
- Materials Science
- Nanotechnology
Background:
- Integrated optics requires miniaturized optical components.
- Mid-infrared (mid-IR) applications demand specialized lens materials and fabrication methods.
Purpose of the Study:
- To demonstrate the fabrication of micrometer-scale mid-IR lenses.
- To utilize solution-based inkjet printing for creating spherical microlenses.
- To investigate the tunability of lens focal length through processing parameters.
Main Methods:
- Solution-based inkjet printing of arsenic sulfide.
- Microlens fabrication with diameters ranging from 10 to 350 μm.
- Post-fabrication processing, including controlled baking conditions.
Main Results:
- Successful fabrication of arsenic sulfide spherical microlenses.
- Demonstrated control over focal lengths from 10 to 700 μm.
- Identified baking conditions as a key parameter for focal length tuning.
Conclusions:
- Inkjet printing is a viable technique for producing mid-IR microlenses.
- Arsenic sulfide microlenses are suitable for integrated optics.
- Precise focal length control is achievable via optimized baking processes.
