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.

摘要翻译：与本公开一致，MZ干涉仪的两个臂是“双折叠”的，并且在至少两个位置弯曲以限定第一和第二锐角内角。因此，MZ干涉仪的臂可以具有基本上相同的长度，此外，MZ干涉仪具有更紧凑的几何形状。在一个示例中，臂彼此平行并具有蛇形形状，并且在另一实施例中，臂彼此平行并具有Z形。因此，由于提供MZ干涉仪的PIC的温度在这么短的距离上没有显着变化，所以两个臂的温度基本相同。

摘要： A photonic integrated circuit (PIC) device comprising two or more vertically stacked asymmetric waveguides is provided. A photo-detector PIC device comprises a coupling waveguide for providing low-coupling loss with an external optical fiber and for guiding primarily a first mode of light, a second waveguide vertically coupled to the first waveguide for guiding primarily a second mode of light having an effective index of refraction different from the first mode, and a photo-detector vertically coupled to the second waveguide. Light received at the coupling waveguide is moved into the second waveguide via a lateral taper in the second waveguide. The photo-detector PIC device may further comprise a third waveguide having an optical amplifier therein and positioned between the coupling waveguide and the second waveguide.

摘要： The present invention provides a polarization converter, and a method for fabricating the same. The polarization converter includes a geometric shape which induces rotation of a polarization of an optical signal from a first polarization state to a second polarization state as the optical signal propagates along the polarization converter. The performance of the polarization converter is maintained in light of inconsistencies in fabrication processes resulting in improved manufacturability.

The laser device comprises a first waveguide having a gain region formed therein for amplifying at least a first mode of light, and a second waveguide vertically coupled to the first waveguide and having a modulator formed therein for modulating a second mode of light having an effective index of refraction different from the first mode. Light propagating in the first waveguide is transferred into the second waveguide via a lateral taper in the first waveguide. The laser device may further comprise a third waveguide positioned between the first and second waveguide for providing isolation between the gain region and modulator.
