Abstract

A monolithic semiconductor device (101) forms a Fabry-Perot sensor (503) when coupled to an optical fiber (501). The monolithic semiconductor device (101) comprises a cavity (108) that extends from a back side (105) to a front side (106) of the monolithic semiconductor device (101). The back side (105) of the monolithic semiconductor device (101) can be coupled to an end (504) of the optical fiber (501). The end (504) of the optical fiber (501) then seals off the cavity (108) in the monolithic semiconductor device (101) at the back side (105). The monolithic semiconductor device (101) comprises a light reflecting membrane (109) that seals off the cavity (108) in the monolithic semiconductor device (101) at the front side (106). The light reflecting membrane (109) is comprised of silicon nitride.
