Embodiments include apparatuses, methods, and systems including a semiconductor photonic device having a substrate, a waveguide disposed above the substrate, a phase change layer disposed above the waveguide, and a heater disposed above the phase change layer. The waveguide has a modifiable refractive index based at least in part on a state of a phase change material included in the phase change layer. The phase change material of the phase change layer is in a first state of a set of states, and the waveguide has a first refractive index determined based on the first state of the phase change material. The heater is to generate heat to transform the phase change material to a second state of the set of states, and the waveguide has a second refractive index determined based on the second state of the phase change material. Other embodiments may also be described and claimed.

A transmission circuit includes an array of subarrays of emitters with quasi-periodic spacing. A first subarray of emitters emits a source signal, and a second subarray of emitters emits the source signal. The first and second subarrays are separated by a subarray spacing that quasi-periodic, wherein the spacing between different subarrays is different. The quasi-periodic subarray spacing is to cause constructive interference of a main lobe of the emissions from the subarrays, and to cause non-constructive interference of sidelobes of the emissions. The spacing between emitters in the subarrays can vary from one subarray to another.

Embodiments of the present disclosure may relate to a hybrid silicon distributed feed-back (DFB) laser, wherein light is to propagate through the DFB laser along a length of the DFB laser. The DFB laser may include a mesa with a current channel that extends from the first side of the mesa to the second side of the mesa. At a first location along the length of the DFB laser, the current channel may have a first width and/or the mesa may have a second width. At a second location along the length of the DFB laser, the current channel may have a third width and/or the mesa may have a fourth width as measured in a direction perpendicular to the length of the DFB laser. Other embodiments may be described and/or claimed.

A slab of a rib waveguide includes geometric disruption features along a direction of propagation of the waveguide. The geometric disruption features scatter optical modes other than the fundamental mode in the slab without significantly impacting the fundamental optical mode that propagates primarily in the rib waveguide. The rib waveguide has a width to constrain the fundamental mode, and the fundamental mode primarily propagates through the rib waveguide, with some of the energy propagated via the slab. When the slab includes edges that are wider than the rib waveguide and smaller than the substrate on which the rib waveguide and slab are integrated, the slab can propagate optical modes other than the fundamental mode, such as higher-order modes. The geometric disruptions scatter the non-fundamental optical modes from the slab. The geometric disruptions can include serration features in one or both edges of the slab.
