Abstract: An adiabatic optical coupler can include: a top tapered region that includes a top taper having two top tapered sides that taper from a first end region to a top tip region, the top taper having a first length; and a bottom tapered region under the top tapered region, wherein the bottom tapered region includes a bottom taper having two bottom tapered sides that taper from the first end region to a bottom tip region, the bottom taper having a second length that is longer than the first length. Another adiabatic optical coupler can include: a tapered region that includes a taper having two tapered sides that taper from an end region to a tip region; and a sub-wavelength grating (SWG) optically coupled with the tip region. Another adiabatic optical coupler can include a combination of these two adiabatic optical couplers.

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: A system includes a grating coupled laser and a photonic integrated circuit (PIC). The grating coupled laser includes a first waveguide and a transmit grating coupler optically coupled to the first waveguide. The PIC includes a second waveguide and a receive grating coupler optically coupled to the second waveguide. The receive grating coupler is in optical alignment with the transmit grating coupler. The receive grating coupler includes a first grating and a second grating spaced apart from and above the first grating within the PIC.
