Abstract

An integrated photonics device (100), such as a thermal phase shifter, for instance, comprises: a substrate of integrated photonics material having an optical waveguide (110) extending therealong as well as first (112a) and second (112b) lateral strips extending sidewise of the optical waveguide (110) and thermally coupled therewith; first (115a) and second (115b) heat transfer formations, such as arrays of copper pillars, configured to transfer heat from a proximal end distanced away from the first lateral strip (112a) and the second lateral strip (112b) in the substrate of integrated photonics material towards a distal end thermally coupled to the first lateral strip (112a) and the second lateral strip (112b) in the substrate of integrated photonics material; and first (130a) and second (130b) electric heaters thermally coupled with the proximal ends of the first (115a) and second (115b) heat transfer formations. Heat generated by the first (130a) and second (130b) electric heaters is transferred to the optical waveguide (110) via the first (115a) and second (115b) heat transfer formations and the first (112a) and second (112b) lateral strips in the substrate of integrated photonics material.
