摘要: 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.

摘要: There is disclosed in one example a fiberoptic communication device, including: a modulator to modulate data onto a laser pulse; and a semiconductor laser source including an active optical waveguide to provide optical gain and support an optical mode, the laser source further including a V-shaped current channel superimposed on the optical waveguide, and disposed to feed the active optical waveguide with electrical current along its length, the current channel having a proximate end to the optical mode, the proximate end having a width substantially matching a diameter of the optical mode, and a removed end from the optical mode, wherein the removed end is substantially wider than the proximate end.

摘要: Embodiments of the present disclosure are directed toward techniques and configurations for a single mode optical coupler device. In some embodiments, the device may include a multi-stage optical taper to convert light from a first mode field diameter to a second mode field diameter larger than the first mode field diameter, and a mirror formed in a dielectric layer under an approximately 45 degree angle with respect to a plane of the dielectric layer to reflect light from the multi-stage optical taper substantially perpendicularly to propagate the light in a single mode fashion. Other embodiments may be described and/or claimed.
