Optical Waveguide Light Guide TRIZ Cases
- Waveguide Modifier Layers for Optical Length Tuning in PICs
Modifier layers tune waveguide optical length by changing effective refractive index, avoiding geometry changes that constrain PIC layout.
- Asymmetric MZI Lattice Filter for Low-Loss Wavelength Multiplexing
Cascaded asymmetric MZI stages replace AWG filtering to cut optical loss, sharpen spectral rectangularity, and shrink transmitter modules.
- Offset-Strip Phase Shifter Structure for High Optical Power
An offset strip beside the waveguide core improves phase tuning while handling higher optical power with less nonlinear absorption.
- Multi-Step Waveguide Tapering for Low-Loss Ridge Modulator Coupling
A multi-step tapered waveguide improves CMBH laser to ridge modulator coupling while reducing capacitance, signal loss, and alignment sensitivity.
