  • Patent number: 12619109
    Abstract: Disclosed are differential-drive electro-optic modulator structures for linear electro-optic (Pockels) platforms such as thin-film LiNbO3 (TFLN), directly compatible with traditional differential-output analog drivers, such as a linear electro-optic modulator, including: a first signal trace; a second signal trace, wherein the first signal trace and the second signal trace are driven by a differential signal; a first optical arm; and a second optical arm, wherein a geometry of the first signal trace and the second signal trace causes the differential signal to modulate optical signals in the first optical arm and the second optical arm, such that when the optical signals are combined to create a resultant optical signal, the geometry mitigates chirp in the resultant optical signal. Other embodiments are disclosed.
