Photopolymerisation Waveguide for optoelectronics

New post-packaging process for optimization of VCSEL - optical fiber coupling 

TECHNOLOGY

• Creates a self-aligned waveguide with graded index
• Based on NIR and UV photo-polymerizations
• Tested on Fiber-Fiber coupling and VCSEL- Fiber coupling configurations
• Validated for Singlemode/Multimode coupling
• Output power increased by 8 times compared to VCSEL- MM fiber coupling in air and 4 times compared to VCSEL- MM fiber coupling in a simple polymer layer

APPLICATIONS

Optoelectronics Packaging:

• Active Alignment with high tolerance
• Coupling optimization
• Crosstalk elimination

INNOVATION ADVANTAGES

• More tolerant to XY misalignment & Z positioning
• Good mechanical resistance
• Transparent
• Quick process
• Enhanced coupling compared to optical gels
