PCT No. PCT/FR93/00038 Sec. 371 Date Jul. 11, 1994 Sec. 102(e) Date Jul. 11, 1994 PCT Filed Jan. 14, 1993 PCT Pub. No. WO93/14378 PCT Pub. Date Jul. 22, 1993A Sagnac effect optical gyrometer is provided. The gyrometer includes a probe including a planar spiral optical loop having light guides for propagating two light waves from a light source. The spiral loop is formed by optical circuits integrated on a substrate. The two light waves traverse the spiral loop in respective directions opposite to each other. The gyrometer also includes a tricoupler having three parallel rectilinear guides, a central guide and two lateral guides. The lateral guides connect two ends of the light guides to respective light detecting means. The central guide is connected on one end to the light source and introduces the light waves into the light guides. The tricoupler is integrated into the same substrate as the spiral loop.
