Precision-tuning lasers will list on the STAR Market on August 18, with an issue price set as the most expensive new stock of the year. Market attention is focused on valuation and the first-day price jump, but from an industry-chain perspective there is one more crucial piece of information: its narrow-linewidth semiconductor laser products sit right at the intersection upstream of two currently popular sectors—optical modules and quantum computing. There are very few domestic manufacturers capable of producing at this level, and they have previously relied mainly on imports. If this fund-raising project clearly targets a self-developed production line for compound semiconductor epitaxial wafers and cavity surface coating processes, it would mean that a traceable domestic substitution example has emerged at one of the most bottlenecked links in optical chips. First-day liquidity won’t be cheap, and the short-term participation value for money is low. What is worth tracking over the medium term is its capacity ramp-up and the pace of customer onboarding, especially the certification progress from quantum communication and silicon photonics module manufacturers.
