A comment on Flip-Chip Integration of a GaSb Semiconductor Optical Amplifier W Si Photonics.
The big point of putting optics on chip, or at least close to the chip is to reduce power consumption.
Huge terabit class router chips spend 1/3 of TDP to drive PHYs.
If you just replace a power hungry copper transmitter with a power hungry optical transmitter, you don't gain in power budget, and lose on cost.
