Odaily News: Paradis Labs stated on the X platform that the key takeaways from Lumentum's earnings call are as follows. 1. EML. Lumentum reported strong EML performance this quarter, driven primarily by 100G-per-channel products. Growth for 200G-per-channel products is "accelerating rapidly," now accounting for over 25% of total EML revenue. Lumentum still expects EML shipments in December 2026 to grow by more than 50% compared to December 2025, even as it shifts some production capacity to CW lasers during this period. Lumentum has added sales of CW laser chips for 200G-per-channel applications to "numerous customers," moving beyond internal use only. The company is expanding two indium phosphide wafer fabs in Japan and is validating production processes for 200G and 300G-per-channel CW lasers and EMLs on its latest equipment. Coherent will report earnings tomorrow, with its business also involving 200G-per-channel EMLs and 400-milliwatt CW lasers. The market is watching whether its 6-inch indium phosphide wafers can deliver a cost advantage, and whether Lumentum will need to respond by improving yields. 2. CPO and NPO. Lumentum stated that the leading CPO customer's production plans "remain on track," with customer demand signals stronger than at the time of the last update. The company now expects laser shipments to begin ramping in the second half of next year, earlier than the customer's large-scale deployment scheduled for 2028. Lumentum has received its first order for ELS modules, with delivery scheduled for the second half of 2027. Other customers are primarily prioritizing NPO as an interim solution. The company said NPO will "bring fully incremental business and significantly expand the total addressable optical market," with even its largest CPO customer evaluating NPO for certain new application scenarios. AAOI expects to ramp ELSFP capacity to approximately 400,000 units per month by 2028. Sivers Semiconductors' external indium phosphide light sources are gradually being adopted for CPO and NPO applications. Lumentum, as the largest commercial laser manufacturer, has already procured products related to the ELS architecture, indicating the architecture has gained validation through real orders. 3. Cloud transceivers and 1.6T. Lumentum's 800G business set a record and began volume shipments of 1.6T products as planned. The company said its visibility into future cloud transceiver demand is "clearer than ever before." The 1.6T business will continue to strengthen from the first fiscal quarter through 2027, driven primarily by hyperscalers' custom AI clusters accelerating the transition from 800G to 1.6T. Lumentum stated that in many cases, it achieved product launch earlier than its larger competitors, and it expects this market share advantage to persist throughout the cycle. Transceiver business profitability is improving, driven by better yields, higher capacity utilization, and an increasing mix of 1.6T products. Lumentum

Odaily News, "White-Haired Stock God" Serenity stated that Lumentum CEO Michael Hurlston has issued a warning that the indium phosphide (InP) laser supply chain for AI data centers is facing a more severe supply gap than memory chips. Even with Lumentum's five InP wafer fabs, product shipments could still fall more than 30% short of customer demand, indicating that AI infrastructure expansion is encountering a critical bottleneck in key optical communication components.Serenity pointed out that current supply pressure is mainly concentrated in the EML (electro-absorption modulated laser) segment, but the InP laser shortage could continue to spread. He remains bullish on the "bottleneck investment" opportunities in the optical communication laser supply chain, keeping an eye on companies including Applied Optoelectronics (AAOI), Sivers Semiconductors (SIVE), Lumentum (LITE), and Coherent (COHR). As AI data center capital expenditures continue to rise, optical modules, lasers, and other infrastructure segments that were previously undervalued by the market are now undergoing repricing, and the InP laser supply bottleneck could become a key limiting factor in the expansion of AI computing power.
According to Semiconductor-Today, Coherent announced that it has signed a Letter of Intent with the U.S. Department of Commerce to secure up to $50 million in direct funding under the CHIPS and Science Act to expand advanced manufacturing capacity for AI photonic chips.
According to the latest 13F filing, as of the end of Q1 2026, NVIDIA’s proprietary investment portfolio held stocks with a total market value of approximately $18.374 billion—significantly up from $13 billion at the end of 2025. The portfolio is highly concentrated in AI-ecosystem-related names (semiconductors, cloud computing infrastructure, EDA, optics, networking, and biopharmaceuticals). Notably, in Q1, NVIDIA increased its stake in CoreWeave by 94.5% to approximately 47.21 million shares, raising the holding’s value by roughly $1.78 billion. It also initiated new positions in Coherent Corp. (approximately 7.8 million shares) and Generate Biomedicines (approximately 833,000 shares). Intel remains NVIDIA’s largest holding, with over 214.7 million shares. This reflects Jensen Huang’s strategic initiative to support the entire AI ecosystem—from chips and cloud computing to networking, photonics, and drug discovery.
