A system may include a wafer that includes ICs and defines cavities. Each cavity may be formed in a BEOL layer of the wafer and proximate a different IC. The system may also include an interposer that includes a transparent layer configured to permit optical signals to pass through. The interposer may also include at least one waveguide located proximate the transparent layer. The at least one waveguide may be configured to adiabatically couple at least one optical signal out of the multiple ICs. Further, the interposer may include a redirecting element optically coupled to the at least one the waveguide. The redirecting element may be located proximate the transparent layer and may be configured to receive the at least one optical signal from the at least one waveguide. The redirecting element may also be configured to vertically redirect the at least one optical signal towards the transparent layer.

Wafer level testing of optical components

In an example embodiment, a system includes a first grating-coupled laser (GCL) that includes a first laser cavity optically coupled to a first transmit grating coupler configured to redirect horizontally-propagating first light, received from the first laser cavity, vertically downward and out of the first GCL. The system also includes a second GCL that includes a second laser cavity optically coupled to a second transmit grating coupler configured to transmit second light vertically downward and out of the second GCL. The system also includes a photonic integrated circuit (PIC) that includes a first receive grating coupler optically coupled to a first waveguide and configured to receive the first light and couple the first light into the first waveguide. The PIC also includes a second receive grating coupler optically coupled to a second waveguide and configured to receive the second light and couple the second light into the second waveguide.

Dual grating-coupled lasers

In one example, an optoelectronic module may include a stack assembly including an electrical integrated circuit and an optical integrated circuit electrically and mechanically coupled to one another, an interposer electrically and mechanically coupled to the stack assembly, and an optical connector to optically couple the optical integrated circuit with an array of optical fibers.

Photonic optoelectronic module packaging

A grating coupled laser (GCL) includes an active section and a passive section. The passive section is butt coupled to the active section to form a butt joint with the active section. The active section includes an active waveguide. The passive section includes a passive waveguide, a transmit grating coupler, and a top cladding. The passive waveguide is optically coupled end to end with the active waveguide and includes a first portion and a second portion. The first portion of the passive waveguide is positioned between the second portion of the passive waveguide and the active waveguide. The transmit grating coupler is optically coupled to the passive waveguide and includes grating teeth that extend upward from the second portion of the passive waveguide. The top cladding is positioned directly above the first portion of the passive waveguide and is absent directly above at least some of the transmit grating coupler.

Grating coupled laser for Si photonics

An optical Mach-Zehnder superstructure modulator and method that can simultaneously linearize in-phase and quadrature components of optically modulated optical signals and reduce the modulated optical insertion loss (MOIL) by in-phase addition of the in-phase and quadrature components of an amplitude and/or phase modulated optical signal using two high-speed phase modulators embedded in the optical Mach-Zehnder superstructure modulator.

Linearization and reduction of modulated optical insertion loss for quadrature optical modulator

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.

Surface coupled laser and laser optical interposer

An integrated optical component includes at least one input waveguide, at least one output waveguide; a first slab waveguide having a first refractive index, n. The first slab waveguide may be disposed between at least one of the input waveguides and at least one of the output waveguides. The integrated optical component may further include a second slab waveguide having a second refractive index, n. The integrated optical component may also include a third cladding slab having a third refractive index, n. The third cladding slab may be disposed between the first slab and the second slab. The thickness of the second slab waveguide and the thickness of the third slab waveguide are adjustable to reduce a birefringence of the integrated optical component.

Polarization independent multiplexer / demultiplexer

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.

Dual layer grating coupler

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.

Adiabatic optical coupler for direct SOI to interposer coupling

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.
