Semiconductor Lasers TRIZ Cases
- Dual-Wavelength Dental Curing Light for Low-Heat Polymer Hardening
A laser diode plus LED wavelength mix cures dental polymers with less heat, better surface finish, and effective hardening at longer distances.
- Eyepiece Waveguide Projection With Polarization Reflectors for Wider FOV
Multiple lasers and polarization selective reflectors tile separate scan angles into a wider, high-resolution eyepiece waveguide image.
- Modular Solid-State LiDAR Layout for Reliable Overlap Scanning
Fixed laser arrays replace moving scanners to deliver overlap-based LiDAR coverage with better reliability, integration flexibility, and lower cross-talk.
- Edge-Emitting Laser Package With Reflected APC Feedback
A reflected beam in the encapsulant feeds a light-receiving chip for auto power control, stabilizing edge-emitting laser output across temperature changes.
- LED Optical Output Control with Updatable Temperature Coefficients
Updatable temperature compensation coefficients let LED current control stay accurate and responsive despite device variation and aging.
- Optical Sensor Packaging With Integrated Filter and Light Masking
Integrated filter and mask layers shrink optical sensor packaging while blocking external light and preserving signal detection.
- Sealed Dual-Grating SBC Assembly for Stable Beam Combining
A sealed fused-silica dual-grating assembly protects SBC gratings from contamination while preserving alignment and beam quality for field service.
- Nanoporous III-Nitride Resonant Cavity Mirror for Ultrafast Index Tuning
A nanoporous piezoelectric layer between DBRs uses acoustic or electric actuation to switch optical resonance in sub-nanosecond time.
- Laser Emission Circuit Calibration for Uniform LiDAR Array Power
Per-laser power detection and control-signal mapping equalize LiDAR array output, reducing point cloud distortion and ranging inconsistency.
- MicroLED Color Conversion Resonators for Narrow-Spectrum RGB Pixels
Resonant color-conversion cavities replace thick, degradable QD layers to deliver narrow-spectrum RGB emission for high-resolution microLED displays.
- Graphite-Metal Submount Structure for LED Heat Dissipation
Layered graphite and metal regions improve heat dissipation in light-emitting submounts while reducing chipping and burrs during cutting.
