Abstract

An implantable optical sensor and associated manufacturing method include a sensor housing having an inner surface and an outer surface and a window formed in the housing extending between the housing inner surface and the housing outer surface. An opto-electronic device enclosed within the housing and having a photonic surface is operatively positioned proximate the window for emitting light through the window or detecting light through the window. An optical coupling member is positioned between the opto-electronic device and the window for reducing light reflection at a surface within the implantable optical sensor.
