Per the Article:

The new platform co-integrates III-V lasers, semiconductor optical amplifiers (SOA), electro-absorption modulators (EAM) and photodetectors with silicon photonics devices, all monolithically on a single chip.

I had not been familiar with an EAM.

From Wikipedia:
Compared with an Electro-optic modulator (EOM), an EAM can operate with much lower voltages (a few volts instead of ten volts or more). They can be operated at very high speed; a modulation bandwidth of tens of gigahertz can be achieved, which makes these devices useful for optical fiber communication.

Anybody anything about this?
