An electro-optic modulator. The modulator is made as a plurality of discrete elements, and adjacent elements abut such that there are no free space optics between adjacent discrete elements. The modulator comprises a radio frequency, RF, element configured to modulate light passing through the element based on an electrical RF input. The plurality of discrete elements comprises a first set of discrete elements fabricated from thin film lithium niobate, TFLN, and a second set of discrete elements fabricated from silicon photonics, SiPh. The first set of discrete elements comprises the RF element.
