Area of Science:

• Optics and Photonics
• Materials Science
• Manufacturing Technology

Background:

• Laser writing systems are susceptible to joint errors, impacting precision and throughput.
• Existing methods like multipass writing and error scattering are time-consuming and reduce fabrication speed.

Purpose of the Study:

• To present a new, efficient method for correcting joint errors in laser writing.
• To achieve joint error correction without compromising throughput.
• To reduce overall fabrication time.

Main Methods:

• Digitization of incident beam intensity data near start and end points.
• Optimization of intensity data to minimize sensitivity to start/end point variations.
• Implementation of a single-pass writing strategy.

Main Results:

• The proposed method effectively corrects joint errors.
• Optimization ensures joint error insensitivity to start/end point lengthening.
• Significant time savings of 80% achieved compared to multipass methods.

Conclusions:

• The novel digitization and optimization method offers an effective solution for laser writer joint errors.
• This single-pass technique enhances efficiency and reduces fabrication time substantially.
• The method presents a viable alternative to conventional error correction strategies.
