摘要： A multifrequency laser (MFL) eliminates nonlinearities produced in the "shared" waveguide of the MFL laser (the section in which all the lightwaves from all the lasers pass) by either making the shared waveguide as short as possible to mimimize the production of mixing product signals or using a channel spacing that is unequal such that any mixing product signals formed from the multifrequency optical laser signal do not overlap in frequency with any of the signals of the multifrequency optical laser signal.

摘要： A method for forming an optical grating within a waveguide integrated on a substrate includes the step of depositing on a substrate successive layers of material constituting a waveguide such that the waveguide has a periodically varying width along a portion of its longitudinal axis. The deposition may be accomplished by depositing by selective area epitaxy at least some of the successive layers through a mask having a periodically varying width along at least one edge. The successive layers deposited through the mask may constitute a plurality of quantum well layers separated from each other by barrier layers which collectively form a multiple quantum well stack.

摘要： Consistent with the present disclosure, both arms of an MZ interferometer are “double-folded” and are bent in at least two locations to define first and second acute inner angles. Accordingly, the arms of the MZ interferometer may have substantially the same length, and, further, the MZ interferometer has a more compact geometry. In one example, the arms parallel each other and have a serpentine shape, and, in a further embodiment, the arms parallel one another and have a Z-shape. Accordingly, since the temperature of a PIC upon which the MZ interferometer is provided does not vary significantly over such short distances, the temperatures of both arms is substantially the same.
