1. An apparatus comprising:
a composite backplane that modulates light from a light source, comprising:
an electronics layer disposed on a substrate;
a photonics integrated circuit (IC) layer disposed on the electronics layer that causes light from the light source to propagate in a first direction; and
an active light modulation (ALM) interface layer disposed on the photonics IC layer controls an active medium layer in order to control the light propagating in the first direction.
