Abstract

An implantable optical sensor having a sapphire window as an optically transparent ceramic micro-scale diffusion bonded to a titanium washer to form a sapphire window/titanium washer assembly is described. The titanium washer is then welded to the inner surface of a device housing in alignment with a housing opening. The micro-scale diffusion bond is formed using an electromagnetic beam emanating from a Gaussian-Bessel laser and has a thickness that is greater than 1 µm, and preferably ≥ 4 µm, with a weld width that is preferably ≥ 45 µm. Importantly, the diffusion bond is spaced from and intermediate undisturbed portions of the optically transparent sapphire and the opaque conductive titanium. A power source connected to an optical sensor aligned with the sapphire window is housed inside the device housing.
