Abstract: An optoelectronic assembly may include a photonic integrated circuit (PIC) with a top surface and a laser with a top surface and a bottom surface. The optoelectronic assembly may also include a housing configured to cooperate with the PIC to one or both of house and support one or more components. The housing may include a PIC mount including a first surface to interface with the top surface of the PIC, and a laser mount including a second surface to interface with the top or bottom surface of the laser. The first surface and the second surface may be parallel to each other.

Abstract: In one example embodiment, a DFB laser includes a substrate; an active region positioned above the substrate; a grating layer positioned above the active region, the grating layer including a portion that serves as a primary etch stop layer; a secondary etch stop layer positioned above the grating layer; and a spacer layer interposed between the grating layer and the secondary etch stop layer.

Abstract: In one example, an optoelectronic assembly may include a laser array, an amplifier array, and a multimode interference coupler optically coupling the laser array and the amplifier array. The laser array may include at least one primary laser and at least one spare laser configured to be activated if the primary laser fails. The amplifier array may include at least two amplifiers configured to amplify optical signals received from the laser array.
