### @datacenter-lasers — Confirmed — cross-validated across both makers' earnings calls
In the same reporting quarter (February 2026), the two leading datacenter-laser makers independently described the same shortage. Lumentum: indium-phosphide fab "fully allocated," under-shipping demand ~25-30%, all EML capacity spoken for through 2027. Coherent: book-to-bill above 4x, capacity doubling by end-2026, yet CEO said demand absorbs all new capacity "and then some" and doesn't foresee balance this year or next. Analyst asked if competitor capacity additions change the picture — answer was yes, still short. When rivals corroborate scarcity under questioning, it stops being marketing.
