  • MONOLITHICALLY INTEGRATED SURFACE EMITTING LASER WITH MODULATOR
    Publication number: 20160043529
    Abstract: A surface emitting laser includes a structure in which a semiconductor substrate, a lower DBR, and an active layer are layered. A VCSEL (vertical cavity surface emitting laser) and an EAM (electro-absorption modulator) are formed adjacent to each other along a first direction defined on the substrate plane such that they are optically coupled. The EAM outputs an emitted light in a direction that is orthogonal to the substrate. The width of a waveguide region of the VCSEL defined in the second direction is narrower than the width of a waveguide region of the EAM.
