Polarisation Multiplex Systems TRIZ Cases
- 4x2 Widely Linear Filter for Optical Signal Distortion Compensation
A 4x2 widely linear filter compensates carrier phase and polarization distortion in optical signals using a unified structure.
- Coherent Receiver Phase Rotation Compensation
Digital signal processor compensates phase rotation from local oscillator frequency differences to stabilize demodulation and improve reception characteristics.
- Silicon Photonic Wavelength Division Multiplexer with Polarization Control
A silicon photonic integrated chip uses polarization control structures and a Mach-Zehnder interferometer to combine optical signals.
- Adaptive Crossing FDE for PolMux Coherent DSP Complexity
Adaptive crossing frequency domain equalization merges chromatic dispersion, polarization mode dispersion, and de-multiplexing into one digital signal processor block.
- Optical Receiver Frequency Domain Equalization for Polarization Multiplexed Signals
Frequency domain equalization unit compensates transmission degradation in polarization multiplexed optical signals using simplified filter coefficients.
- Hybrid Polarization Demultiplexer Bandwidth Loss Trade-off
A hybrid polarization demultiplexer merges thermo-optic and electro-optic phase shifters to separate polarized optical signals.
