Photon Capital(@PhotonCap):If you have been reading PhotonCap from the start, you know these names. IQE and AXT from the substrate series. Coherent from the subsea cable series. All three appear again in this article. III-V compound semiconductor is the material tier connecting optical communications, satellites, subsea cables, and defense. The same InP, GaAs, and GaN wafers go into lasers, radars, and IR sensors. This article shows how those materials become money in defense sensors, mapped across 28 listed companies. On the first day of war, platforms rally. When war drags on, sensors make the money.
