摘要： A photonic integrated circuit is provided that is adapted to compensate for an unintentional manufactured refractive index profile, such as a gradient, that arises due to manufacturing variance. The photonic integrated circuit including at least a thermal source and a spaced thermal sink to induce a thermal gradient in the photonic integrated circuit between the thermal source and the spaced thermal sink, the thermal gradient imparts an opposing thermal refractive index profile to correct for the manufactured refractive index profile. In some embodiments the photonic integrated circuit may be constructed with features that have an intentional structured refractive index profile that ensures any unintentional manufactured refractive index profile is correctable by the opposing thermal refractive index profile induced by the thermal source.

摘要： Aspects of the disclosure provide a system and method used for time-of-flight lidar applications. Such systems and methods include a laser and pulse clipper which produces a shuttering effect to reduce the instantaneous output power from the pulse clipper. Accordingly the output from the pulse clipper is more suitable for time-of-flight lidar applications than that initially produced by the laser. This can allow for lasers which may otherwise exceed eye safety limits to be used for time-of-flight lidar applications without exceeding the eye safety limits.

摘要： Optical inputs to photonic switches may incorporate a polarization controller in order to change the polarization of the input signal to a pre-determined polarization for operation with the silicon photonics. A last stage of components of the polarization controller may overlap with a first input switching stage. A polarization controller that overlaps with the first stage of the switch input may provide lower insertion loss and power consumption for the photonic switch.
