Article Synopsis
- A new configuration for a mode-dependent-loss (MDL) equalizer is introduced for systems using two linearly-polarized modes on a silica planar lightwave circuit.
- The device functions as an LP-mode attenuator, ensuring high transmission of LP modes while adjusting MDL.
- A newly designed E/E mode converter is crucial for achieving broadband MDL equalization, with transmission spectra optimized for wavelengths between 1200 nm and 1650 nm.
Article Synopsis
- A new silica-based LP mode rotator for space division multiplexing is introduced, showcasing multiple tapered trenches for improved performance.
- This design outperforms traditional L-shape waveguide models in terms of mode conversion efficiency, insertion loss, and fabrication tolerance due to its adiabatic mode conversion principle.
- Utilizing a shortcut to adiabaticity allows for effective miniaturization of the device, making it a strong candidate for future silica-based mode multi/demultiplexers.
