Abstract
An integrated parallel transmitter includes an array of light sources, a corresponding array of diffractive elements splitting off a portion of the beam to be monitored, a corresponding array of power monitors for respectively monitoring each light source, and an array of couplers that couples light into a corresponding waveguide. The coupler is preferably a phase-matched coupler. All of the passive optical elements are integrated onto a single substrate or a plurality of substrates that have been bonded together on a wafer level.
