A good article and underpins (potentially) some of the recent narrative coming from Nanoco.
It's nice to read phrases like "SWIR VCSELs should be based on indium phosphide (InP)" and "will have to be based on InGaAs material or use quantum dots" and “In both cases, the technology is still emerging, manufacturing yields are low, and availability of components is limited. This will lead to higher component costs for both the emitter and the receiver”
However our dots don't use InP as it also has carcinogenic potential so this is a positive Nanoco need to be pushing. Nanosys I believe use InP. InP I can see as a potential issue more in the use of personal devices than display/auto.
"The Yole team concludes that, as a result, only Apple - whose phones now sell for more than $1000 - could afford such a profound technology shift."
Well let's hope STMicro are working with Apple on this but it sounds like Automotive LIDAR is another avenue with potential.
My views on InP are from memory so please feel free to pick it apart.
