Embodiments disclosed herein include an on-cavity photonic integrated circuit (OCPIC). In an embodiment, the OCPIC comprises a laser transmitter, that comprises a row with four bumps, and a micro-ring resonator (MRR) in the row between a first bump and a second bump of the four bumps. In an embodiment, a cavity is below the MRR, where a diameter of the cavity is substantially equal to a spacing between the first bump and the second bump.

On-cavity photonic integrated circuit (OCPIC) to achieve the most undercut real estate for effective thermal tuning

Embodiments disclosed herein include an optoelectronic system. In an embodiment, the optoelectronic system comprises a first substrate, a second substrate over the first substrate, and a micro-ring resonator (MRR) over the second substrate. In an embodiment, a heater is integrated into the MRR, a cladding is over the MRR, and a temperature sensor is over the MRR in the cladding.

Embodiments disclosed herein include photonics systems with a dual polarization module. In an embodiment, a photonics patch comprises a patch substrate, and a photonics die over a first surface of the patch substrate. In an embodiment, a multiplexer is over a second surface of the patch substrate. In an embodiment, a first optical path from the photonics die to the multiplexer is provided for propagating a first optical signal, and a second optical path from the photonics die to the multiplexer is provided for propagating a second optical signal. In an embodiment, a Faraday rotator is provided along the second optical path to convert the second optical signal from a first mode to a second mode before reaching the multiplexer.

Embedded faraday rotators and components for increasing bandwidth and/or reducing fiber count in photonics multi chip packages

Embodiments described herein may be related to apparatuses, processes, and techniques related to a dual polarization chiplet that may be used by an optical receiver to split multi-polarized light traveling on a single fiber and carrying two or more light signals into two or more fibers each carrying the particular light signal. The dual polarization chiplet may also be used by an optical transmitter to combine multiple light signals to be transmitted onto a single fiber, where each of the multiple light signals are represented by a different polarization of a wavelength on the single fiber. Other embodiments may be described and/or claimed.

Converting multiple light signals into and out of a single wavelength with multiple polarizations to increase optical bandwidth

Embodiments described herein may be related to apparatuses, processes, and techniques related to a bidirectional optical grating coupler that may be used for testing. A photonic apparatus includes a first layer with electro-optical circuitry that is optically coupled with a bidirectional optical grating coupler. A second layer is physically coupled with a first side of the first layer and includes a first light path to optically coupled with the bidirectional optical grating coupler. A third layer is physically coupled with a second side of the first layer opposite the first side of the first layer, and includes a second light path that optically couples with the bidirectional grating coupler. Operational testing of the electro-optical circuitry is based in part on light received or transmitted through the second light path. Other embodiments may be described and/or claimed.
