Optical Mode Multiplex Systems TRIZ Cases
- Few-Mode Optical Amplifier with Mode Exchange for DMG Equalization
Two serial few-mode EDFAs with a mode exchanger balance complementary gains to reduce differential mode gain in mode-division multiplexing.
- OAM Photon Source Multiplexing for High-Dimensional Quantum Communication
Multiple optical channels use orthogonal OAM phase masks and combining optics to raise quantum data capacity in one encoded beam.
- Few-Mode Fiber Multiplexing with Combined Degenerate Modes
Combining degenerate fiber modes into one data channel cuts crosstalk while preserving low-loss transmission and signal separation.
- Multi-Core Fiber Monitoring with Crosstalk-Corrected Reception
Looped-back optical pulses and corrected reception levels compensate for core crosstalk, improving failure detection in multi-core fiber paths.
- Integrated Optical Chip for Multimode Fiber Wavefront Pre-Compensation
On-chip intensity, phase, time-delay, and polarization control improves multimode fiber pre-compensation while reducing space and complexity.
- Optical Waveguide Bend Measurement Using Higher-Order Mode Detection
Primary-mode content at a second wavelength reveals optical waveguide bending, helping verify routing margins and reduce coupling loss.
