Avicena 下一关：评估套件之后，怎样走向可维护的 MicroLED 系统？
连接器怎样影响数百条光通道？用原始光纤阵列、串扰 BER 与主机接口图，讲清插拔公差、诊断、重训练和系统验收。
CEA / PSMC：怎样把 GaN 通信器件变成代工平台？
用晶圆转移流程、GSG 接入和带宽—电流密度实测曲线，拆清 CMOS 兼容、模型、PDK、3D 接口与批次良率。
Credo / Hyperlume：如何把可靠性带到更远距离？
用公开申请原图与理论表，解释色散、NA、距离、冗余光源、通道切换与遥测；不把 30 米方向写成完整实测。
显示与照明厂商转向 MicroLED 通信，还缺什么？
从富采组件原表和 ams OSRAM 装配原图，比较显示制造能力的迁移与 die、转移、驱动、PD 及全链路验收短板。
