Abstract
A ring resonator waveguide for a laser gyroscope comprises a ring of waveguide material (2) formed around the inside or outside surface of a hollow cylinder (3) or ellipsoid (4). Such a ring resonator waveguide is made by providing a hollow cylindrical substrate (1), depositing waveguide material (2) on the inside or outside surface of the hollow cylindrical substrate (1), heating the substrate (1) and blowing it to form a cylindrical or ellipsoidal (4) member, and cutting a circular section (5, 6) from the cylindrical member (3) or from a central portion of the ellipsoidal member (4).
