1. An integrated light source module, comprising:
a planar optical waveguides layer having N light incident ports aligned with respect to each other, M light exit ports aligned with respect to each other, and optical waveguides connected to the N light incident ports and the M light exit ports; and
N laser diodes or light emitting diodes facing each of the N light incident ports so that light emitted from each of the N laser diodes or light emitting diodes can be incident on each of the N light incident ports;
a substrate with the planar optical waveguides layer on an upper surface of the substrate; and
a subcarrier with the N laser diodes or light emitting diodes on an upper surface of the subcarrier;
wherein the substrate is connected to the subcarrier via a metal layer, and light emitted from the M light exit ports can be applied to an object to be irradiated.
