摘要： A hybrid distributed feedback (DFB) laser formed from III-V and silicon materials can include a grating in the III-V material to provide optical feedback for mode selection. The grating can include a shift feature in a middle or other parts of the grating to change light output from the gain region. The grating can be a top-surface grating or regrowth can be applied to the III-V structure, which can then be bonded to a silicon structure to couple DFB laser light from the III-V structure to one or more silicon waveguides in the silicon structure.

摘要： A symmetric distributed feedback (DFB) laser that is integrated in a silicon based photonic integrated circuit can output light from both sides of the symmetric DFB laser onto waveguides. The light in the waveguides can be phase adjusted and combined using an optical coupler. The symmetric DFB laser can generate light and symmetrically output light onto different lanes of a multi-lane transmitter.
