Waveguide quality inspection in quantum cascade lasers: A capsule neural network approach

作者:

Highlights:

• A deep learning model to classify anomalies in optoelectronic wafers.

• Defects and dirt accumulated in waveguide were the two anomalies investigated.

• The deep learning approach combines CNN and WaferCaps by parallel decision fusion.

• Image data for analysis were collected from laser manufacturer in Europe.

• The results showed the importance of using the decision fusion approach.
