Abstract: A method of generating multiple channels of optical pulses comprises: providing a continuous wave optical input having an optical power; dividing the optical power of the optical input into equal consecutive slices in the time domain; and allocating the consecutive slices sequentially to two or more optical outputs such that each output forms a channel of optical pulses of equal pulse repetition rate shifted in time relative to the or each other channel.

Abstract: An optical modulator. The optical modulator comprising: a micro-ring resonator; and a bus waveguide, including an input waveguide region, an output waveguide region, and a coupling waveguide region optically coupled to the micro-ring resonator and located between the input waveguide region and the output waveguide region. The micro-ring resonator includes a modulation region, the modulation region being formed of a silicon portion and a III-V semiconductor portion separated by a crystalline rare earth oxide dielectric layer.

Abstract: A method of manufacturing a photonic chip. The method comprises providing a wafer comprising a silicon substrate, and a low refractive index layer above the silicon substrate, forming a first trench having a first height and a second trench having a second height by etching the low refractive index layer. The second height is greater than the first height and the second trench has a bottom surface that is closer to the substrate than a bottom surface of the first trench.
