Overview: The Annual Silicon Photonics and Co-Packaged Optics Report highlights how the rapid advancement of AI is driving explosive growth in demand for high speed, high capacity data transmission, outpacing the capabilities of traditional optical modules. Co-Packaged Optics (CPO) has emerged as a key solution, offering reduced loss, lower power consumption and high integration by shortening the distance between the switching chip and optical engine. Silicon Photonics (SiPh), the ideal technology for enabling CPO, is central to reshaping data center and networking infrastructure to meet growing bandwidth and energy efficiency needs. As a result, global optical communication transceiver revenue is projected to grow at a CAGR of 18.6% from 2025 to 2033.
