Specialty analog foundry Tower Semiconductor Ltd of Migdal Haemek, Israel, in collaboration with Quintessent Inc of Santa Barbara, CA, USA, which specializes in laser integration with silicon photonic integrated circuits (PICs), have announced what they claim is the first heterogeneous integration of gallium arsenide (GaAs) quantum dot (QD) lasers and a foundry silicon photonics (SiPho) platform (PH18DB). This PH18DB platform is targeted at optical transceiver modules in data centers and telecom networks, as well as new emerging applications in artificial intelligence (AI), machine learning (ML), light detection & ranging (LiDAR) and other sensors. According to the market research firm LightCounting, the silicon photonics transceiver market is expected to rise at a compound annual growth rate (CAGR) of 24%, reaching a total addressable market (TAM) of $9bn in 2025.
