Semiconductor Type:
Optoelectronics
Optoelectronics refers to semiconductor devices that generate, detect, or modulate light. These devices underpin applications from consumer displays and datacenter interconnects to LiDAR, photovoltaics, and medical imaging. Built primarily on III–V compound semiconductors (GaAs, InP, GaN) and increasingly silicon photonics, optoelectronics enables high-speed data transmission, advanced sensing, and efficient lighting.
Role in the Semiconductor Ecosystem
- Provide light emission (LEDs, lasers) and light detection (photodiodes, avalanche detectors, SPADs).
- Serve as the backbone of fiber-optic communications in datacenters and telecom networks.
- Enable 3D sensing in smartphones, AR/VR headsets, robotics, and automotive LiDAR.
- Critical for clean energy (solar PV cells) and solid-state lighting (LED, microLED).
- Drive material innovation in GaAs, GaN, InP, SiC, and hybrid silicon photonics.
Device Categories
- LEDs & MicroLEDs: General lighting, displays, automotive headlights, emerging AR/VR microdisplays.
- Laser Diodes: VCSELs, edge-emitting lasers, quantum cascade lasers for LiDAR, datacom, sensing.
- Photodiodes & Detectors: PIN, APD, SPAD detectors for optical comms, LiDAR, and scientific imaging.
- Silicon Photonics: Integrated optical circuits for datacenter interconnects and co-packaged optics.
- Optical Modulators: Electro-absorption and Mach–Zehnder modulators for high-speed optical links.
- Displays: OLEDs, MicroLEDs, quantum-dot displays in consumer electronics.
