Abstract
A method for manufacturing an optical wafer may include coating multiple optical components with a substrate. The multiple optical components may include a light emitting component and a light detecting component, and each of the optical components may include one or more electrical connections. The method may also include depositing a redistribution layer onto at least one of the electrical connections, wherein the redistribution layer routes the electrical connection within the optical wafer to an external connection. The method may also include depositing a passivation layer over the redistribution layer and depositing a dark photoresist layer on at least the passivation layer. The photoresist layer may operatively reduce optical interference between at least one light emitting component and at least one light detecting component.
