I would add that the original assessment/report from last year had applications associated with 1310nm to 1550nm (O to S band). The optical interposer has been found to be applicable to a much wider range of wavelength and is not constrained by frequency. So higher data rates (frequency) and a broader range of application from the visible light spectrum  to long haul data transmission. I think one of the really big areas that will be pushed is sensing for automotive applications because that is a huge area of growth with the advent of autonomous cars. Interesting background being discussed in the off topic re Maumita Chakrabarti, Ph.D. Principal Engineer Denselight Semiconductors and her background in medical imaging.
