Abstract: In one example embodiment, an optical circuit for optical modulation of light may include an input waveguide including a first thickness, an optical modulator including a second thickness, and a tapered transition that optically couples the optical modulator and the input waveguide. The second thickness may be smaller than the first thickness. The tapered transition may adiabatically transform the optical mode of the input waveguide to the optical modulator.

Abstract: A PCR can include: a substrate; a primary through waveguide formed in the substrate having a custom tapered top region over a bottom region; a secondary cross waveguide formed in the substrate having a custom body shape; and a gap between the primary through waveguide and secondary cross waveguide. The custom tapered top region forces the TM mode to convert to a TE mode and cross into the secondary cross waveguide.

Abstract: An optical waveguide may include a silicon portion and a silicon nitride portion positioned over the silicon portion. The silicon portion may include a taper that decreases a width of the silicon portion. The optical waveguide may include a transition between a loaded single mode or multimode waveguide to a single mode waveguide. The silicon nitride portion may confine optical signals traveling through the optical waveguide in the silicon portion.

Abstract: An example system includes a grating coupled laser, a laser optical interposer (LOI), an optical isolator, and a light redirector. The grating coupled laser includes a laser cavity and a transmit grating optically coupled to the laser cavity. The transmit grating is configured to diffract light emitted by the laser cavity out of the grating coupled laser. The LOI includes an LOI waveguide with an input end and an output end. The optical isolator is positioned between the surface coupled edge emitting laser and the LOI. The light redirector is positioned to redirect the light, after the light passes through the optical isolator, into the LOI waveguide of the LOI.

Abstract: In an example, a photonic system and method include a photonic integrated circuit (PIC) including a silicon (Si) waveguide and a first silicon nitride (SiN) waveguide. The system also includes an interposer including a second SiN waveguide including vertical tapers on the second SiN waveguide by increasing a thickness of the second SiN waveguide in a direction toward the first SiN waveguide to allow an adiabatic optical mode transfer and decreasing the thickness of the second SiN waveguide in a direction away from the first SiN waveguide to inhibit the optical mode transfer.
