A carrier laser device assembly is provided in which a visible region of a laser that includes an output portion and/or output portion of a waveguide of the laser is visible to an imaging system when the laser is attached to a carrier. The laser may be burned-in and/or tested prior to attachment to a photonic integrated circuit. The output portion and/or output portion of waveguide may be aligned with a corresponding input portion and/or input portion of a waveguide of the PIC as the laser assembly is being attached to the PIC via imaging of the visible portion by the imaging system.

Carrier based laser assembly and method of assembly thereof with photonic integrated circuit

A single laser multi-frequency transmitter is provided, comprising: a laser generating given modes; an optical input bus; a common optical output bus; coupling optics coupling the laser to the optical input bus; a plurality of ring resonator filters: arranged in series along the optical input bus in a one-to-one relationship with a sub-band of the given modes; optically coupled to both the optical input bus and the common optical output bus; and each configured to couple one respective frequency from the sub-band to the common optical output bus; and, a plurality of ring resonator modulators: arranged in series along the common optical output bus in a one-to-one relationship with the plurality of ring resonator filters; and each configured to modulate one given respective frequency from the sub-band so that all modes in the sub-band are modulated on the common optical output bus.
