POET Technologies Provides Purchase Order Update

POET Technologies announced that all purchase orders from Celestial AI for optical engines and light sources designed for artificial intelligence networks have been cancelled following Marvell Semiconductor's acquisition of Celestial AI. Marvell provided written notice on April 23, 2026, citing POET's alleged breach of confidentiality obligations through public disclosures of purchase order details and shipping information. The cancelled orders included initial production units that POET had first announced in April 2023, representing a significant setback for the optical component manufacturer's AI infrastructure business. The cancellation highlights the challenges faced by optical technology suppliers in the rapidly consolidating AI hardware market. POET specializes in highly-integrated optical engines that enable high-speed data transmission in AI networks, a critical component as data centers scale to support increasingly demanding machine learning workloads.
