摘要： An assembly with optical gain assisted optical transposer is provided. The optical transposer which optically couples a fibre array unit and a photonic integrated circuit. The optical transposer includes one or more optical gain elements which are configured to provide optical compensation, for example optical gain to mitigate optical losses associated with multistage photonic integrated devices. According to some embodiments, the optical gain element is a semiconductor optical amplifier (SOA). According to some embodiments the photonic integrated circuit is a SiPh PIC.

摘要： The present application provides an electrostatic discharge guard structure for photonic platform based photodiode systems. In particular this application provides a photodiode assembly comprising: a photodiode (such as a Si or SiGe photodiode); a waveguide (such as a silicon waveguide); and a guard structure, wherein the guard structure comprises a diode, extends about all or substantially all of the periphery of the Si or SiGe photodiode and allows propagation of light from the silicon waveguide into the Si or SiGe photodiode.

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.
