1. **[The More Anthropic Buys Micron HBM, the Faster Optical Memory Pooling Arrives](https://photoncap.net/p/the-more-anthropic-buys-micron-hbm)**  
   Optics expert [PhotonCap](https://substack.com/profile/401123740-photoncap) uses the recent Micron and Anthropic agreement as a starting point to explain why the memory bottleneck in AI infrastructure is becoming a structural problem.
   The piece breaks down why HBM shortages are lifting the broader DRAM market, and why the next path toward memory disaggregation may make optics increasingly important.

2. **[The War of Light Has Begun](https://damnang2.substack.com/p/the-war-of-light-has-begun)**

   $AAOI may be one of the most controversial optical stocks in the market. Just look at the analyst price targets. They range from as low as $57.50 to as high as $220. Investors and analysts are looking at the same company, yet some believe it is far too expensive, while others still see significant upside.
