Polarisation Multiplex Systems TRIZ Cases
- Polarization-Multiplexed Signal Receiver for Digital IQ Restoration
A splitter, photodetectors, ADCs, and digital processing restore IQ and baseband signals without precise orthogonal polarization control.
- Injection-Locked Optical Transmitter for Legacy Fiber Capacity
A master seed laser injection-locks slave lasers so legacy fiber networks can increase capacity while using simpler receiver hardware.
- Multi-Wavelength Optical Receiver With Ring Resonator Delay Matching
A polarization diversifier, ring resonator filter, and unequal waveguide lengths synchronize TE and TM arrivals at the photodetector.
- Co-Packaged Optics With Bidirectional Laser Fiber
Polarization splitter rotators route both polarizations through one bidirectional medium, reducing fiber breakouts, cost, and complexity.
- Multi-Peak Constellation Shaping to Reduce Fiber Nonlinearity
This case uses multiple distribution maxima to limit nonlinear impairments while preserving transmission capacity and spectral efficiency.
