90 Degree Optical Hybrid

90 Degree Optical Hybrid

Features

• Purely passive device (no need for external electric power)
• Compact size
• Based on free-space bulk-optics design
• DPSK modulation is a prerequisite for adapting coherent detection

• For coherent signal demodulation and detection
• For the next-generation optical transmission system
• Key component for the optical coherent detection (a detection format which has been widely used in many other communication methods, such as radio and wireless)
