TSMC utilizes COUPE platform to lead in co-packaged optics technology
Friday, March 13, 2026 at 02:34 AM
TSMC is emerging as a technology leader in the Co-Packaged Optics (CPO) market, utilizing its proprietary COUPE (Compact Universal Photonic Engine) advanced packaging platform to integrate optical interconnects with silicon chips.
Context
As of March 2026, TSMC has established its COUPE (Compact Universal Photonic Engine) platform as the industry standard for co-packaged optics (CPO), addressing the critical "power wall" in AI data centers. By utilizing SoIC-X chip stacking technology to integrate electrical and photonic dies, the platform achieves over 50% energy savings compared to traditional DSP transceivers. This shift is vital for hyperscalers managing trillion-parameter AI models, where data transmission previously consumed up to 30% of total system power.
The commercial roadmap is accelerating, with NVIDIA and Broadcom already integrating COUPE into their next-generation optical engines. TSMC plans to qualify the technology for small form factor pluggables this year, followed by full CoWoS integration in 2027. This timeline coincides with a massive 27–37% year-over-year increase in TSMC’s 2026 capital expenditure, signaling a definitive transition from electrical to optical signaling to sustain the global semiconductor market's path toward $1 trillion by 2030.
