Nanoscale Imaging Probe Printed onto Tip of Optical Fiber
Industry users and Molecular Foundry scientists have developed a way to print nano-optical devices onto the tip of a glass fiber.
Significance and Impact
Nano-optics could help improve solar cells, design better drugs, and make faster semiconductors. This fabrication technique accelerates the device production from several per month to several per day, bringing mass fabrication to nano-optical devices.
- A single mold with precise nanoscale dimensions can produce many nano-optical devices.
- IR light is used to position the mold and UV is used to harden a special resin that fills the mold.
- The approach has created various nano-optical devices, such as the Foundry’s Campanile probe, microscopic lenses and beam splitters.
