Abstract: Integrated photonic devices, packages, and systems are disclosed. An example photonic device includes a laser device with a laser cavity having three sections. The three sections include, respectively, an active region, a waveguide, and a grating arranged along a longitudinal axis of the cavity. Materials of these three sections of the laser device are selected so that a TOC of the grating is between a TOC of the active region and a TOC of the waveguide.

Abstract: Embodiments herein relate to an optical system coupled with or including a control logic. The control logic may be configured to identify, based on feedback provided by a photodiode (PD) of an optical receiver, that an amplitude of an optical marker signal output by an interferometer of the optical receiver is above a threshold value. The control logic may further be configured to adjust, based on the identification, a thermo-optic phase tuner of the interferometer, wherein adjustment of the thermo-optic phase tuner results in a change to the amplitude of the optical marker signal. Other embodiments may be described and/or claimed.
