Core Insights - The article discusses the evolution of optical interconnect technology, highlighting three key structural patterns in the market: vertical integration vs. specialization, the scarcity of light generation, and the rise of SiPho foundries [5][6][10]. Group 1: Market Structure - Vertical integration offers structural advantages during technological transitions, as companies that can design across multiple layers can optimize the entire tech stack [9]. - Companies like Broadcom exemplify vertical integration, appearing across multiple layers of the value chain, while most others focus on specific segments [8]. - The semiconductor industry has historically shown that such advantages may not be permanent, as standardization can lead to the emergence of fabless models [9]. Group 2: Scarcity of Light Generation - The difficulty of producing light sources (Layer 1 and Layer 0) is highlighted, with InP and GaAs materials requiring specialized technology and equipment [12][13]. - Companies capable of mass-producing high-performance InP lasers are few, creating a concentrated market [13][14]. Group 3: Rise of SiPho Foundries - Layer 2, which focuses on SiPho foundries, is gaining attention as traditional semiconductor manufacturers like TSMC and GlobalFoundries enter the photonics space [17]. - TSMC's potential to optimize both AI chips and optical interconnects within the same ecosystem could disrupt existing vertical integration advantages [17]. Group 4: Layer Analysis - Layer 0 involves substrate supply, with companies like AXT benefiting from increased demand for III-V substrates, although geopolitical risks exist due to production in China [21][22]. - Layer 1 is dominated by Coherent and Lumentum, both of which manufacture InP lasers and are expanding production amid high demand [24][25]. - Layer 2 focuses on SiPho foundries, with companies like GlobalFoundries and TSMC leading in manufacturing photonic integrated circuits [27][29]. - Layer 3, represented by DSPs, faces potential obsolescence as CPO technology advances, with companies like Broadcom and Marvell adapting to this shift [33][36]. - Layer 4 sees companies like Innolight and Eoptolink currently leading in the pluggable module market, but their positions may be challenged as the industry shifts towards CPO [40][42]. Group 5: Future Signals - Key indicators to watch include pJ/bit energy consumption metrics, which reflect technological advancements and efficiency [56]. - The ongoing standardization efforts, such as OIF and UCIe, will shape the future market landscape and influence competitive dynamics [57][59]. - Recent mergers and acquisitions signal strategic directions in the industry, with notable deals like Marvell's acquisition of Celestial AI [60][62]. - The choices made by major cloud service providers like Google and AWS regarding their technology partnerships will ultimately determine market trajectories [63][64].
