Abstract: An optical coupling device can couple incident light, propagating orthogonal to a layered structure, into a layer of the layered structure. The device can include a lens having a lens central axis. The lens can focus a first beam to form a converging second beam. The first beam can have a first beam central axis that is offset from the lens central axis. The second beam can have a second beam central axis that is angled with respect to the first beam central axis. A planar grating can redirect the second beam to form a converging third beam. The third beam can have a third beam central axis that is parallel to a plane of the grating. Offsetting the first beam central axis from the lens central axis in this manner can help relax wavelength, manufacturing, and/or alignment tolerances, compared to a configuration in which there is no offset.

Abstract: Embodiments of the invention describe apparatuses, optical systems, and methods related to utilizing optical cladding layers. According to one embodiment, a hybrid optical device includes a silicon semiconductor layer and a III-V semiconductor layer having an overlapping region, wherein a majority of a field of an optical mode in the overlapping region is to be contained in the III-V semiconductor layer. A cladding region between the silicon semiconductor layer and the III-V semiconductor layer has a spatial property to substantially confine the optical mode to the III-V semiconductor layer and enable heat dissipation through the silicon semiconductor layer.

Abstract: Embodiments of the invention describe apparatuses, optical systems, and methods for utilizing a dynamically reconfigurable optical transmitter. A laser array outputs a plurality of laser signals (which may further be modulated based on electrical signals), each of the plurality of laser signals having a wavelength, wherein the wavelength of each of the plurality of laser signals is tunable based on other electrical signals. An optical router receives the plurality of (modulated) laser signals at input ports and outputs the plurality of received (modulated) laser signals to one or more output ports based on the tuned wavelength of each of the plurality of received laser signals. This reconfigurable transmitter enables dynamic bandwidth allocation for multiple destinations via the tuning of the laser wavelengths.
