Abstract:
1. A method of electrically isolating spatially disposed semiconductor electro-optic components integrated on a substrate, where a first electro-optic component is operated with a first bias current with a steady state condition and a second electro-optic component is operated with a second bias current with modulated variations in accordance with an electrical modulated signal applied to the second electro-optic component, comprising the steps of: activating the electro-optic components with the first and second applied bias currents whereby an undesired parasitic current is established along a first electrical path between them, the parasitic current also transferring modulated variations created at the second electro-optic component over to the first electro-optic component via the first electrical path so that the latter no longer operates in its steady state condition; establishing an electrical isolation region between the first and second electro-optic components to create a second electrical path transverse to the first electrical path; and applying a bias at a bias point at the electrical isolation region to divert the parasitic current from the electrical first path through the second electrical path to the bias point resulting in divided parasitic currents, respectively, between the first electro-optic component and the bias point and between the bias point and the second electro-optic component so that the undesired modulated variations along the first electrical path are substantially eliminated from affecting the first electro-optic component.
