Optical Waveguide Light Guide TRIZ Cases
- Non-linear Waveguide Taper for Compact Optical Power Splitter
Curved waveguide transitions reduce insertion loss and cross-talk while maintaining a compact footprint in photonics chips.
- Silicon Thermal-Optic Phase Shifter with P-i-N Diode Structure
Reverse biasing the p-i-n diode mitigates two-photon absorption effects, reducing free-carrier absorption losses in high-power silicon photonic applications.
- Evanescent Coupled Photodetector Bandwidth Capacitance Trade-off
A secondary passive waveguide evanescently couples optical signals to an active layer for high responsivity.
- Light Guide Member Groove Angles for Uniform Luminance
First grooves with increasing reflective face angles and second grooves with constant vertical angles eliminate dark areas in backlight units.
- Self-aligning Photonic Interconnects for PIC Assembly
Angled waveguide intersections provide evanescent coupling that relaxes stringent alignment precision requirements for photonic integrated circuits.
- Silicon Nitride Echelle Grating WDM Multiplexer
Auxiliary waveguides with tapered ends confine optical modes and reduce crosstalk in temperature-sensitive silicon photonics.
- Waveguide Lateral Strips for Spurious Mode Filtering
Lateral strips with varying thickness and absorbing material filter spurious modes while maintaining guided mode transmission.
- Bridge-Waveguide for Silicon Electro-Optical Coupling
A bridge-waveguide links a silicon waveguide to an electro-optically active stack using refractive index matched filling material.
