PCT No. PCT/EP93/02977 Sec. 371 Date Aug. 9, 1995 Sec. 102(e) Date Aug. 9, 1995 PCT Filed Oct. 27, 1993 PCT Pub. No. WO94/10598 PCT Pub. Date May 11, 1994The invention relates to an optical modulator allowing to modulate a coherent light beam (2) by an optical signal (4). According to the invention, it comprises an optical cavity (3) composed of two superposed glass substrates (8, 9), each carrying an interferometric tridimensional lattice, said coherent beam (2) being susceptible to be directed on a first surface of said cavity (3), whereas said optical modulation signal (4) is directed against said first surface or the opposite surface of this cavity, the output signal of this modulator being constituted by said beam after reflection on said optical cavity (3).
