Abstract:
A chemical sensor, including a porous optical waveguide. The loss or index of refraction, or both, of the porous waveguide is affected by the presence of one or more chemicals of interest.

Claim (Index 15):
The method of  claim 14 , wherein the fabricating of the starting wafer comprises:\n fabricating a first wafer, the first wafer comprising:\n a silicon substrate, and \n a layer of silicon dioxide on the silicon substrate; \n fabricating a second wafer, the second wafer comprising:\n a silicon substrate, \n a high-porosity porous silicon layer on the silicon substrate, and \n a low-porosity porous silicon layer on the high-porosity porous silicon layer, the low-porosity porous silicon layer having lower porosity than the high-porosity porous silicon layer; \n bonding together the first wafer and the second wafer to form a bonded assembly; and cleaving the bonded assembly at the low-porosity porous silicon layer to form a bonded wafer, the bonded wafer having a top surface of porous silicon.
