PCT No. PCT/GB97/00266 Sec. 371 Date May 4, 1998 Sec. 102(e) Date May 4, 1998 PCT Filed Jan. 30, 1997 PCT Pub. No. WO97/28481 PCT Pub. Date Aug. 7, 1997An optical fibre is formed with longitudinal recesses (11, 12) which extend toward its core (3) through cladding region (2). The recesses receive electrode structures (20a, b) made of glass, which include tongues (23a, b) that fit into the recesses, on which metal electrode strips (a, b) are formed. A potential difference applied between the strips (a, b) can induce electro-optic effects in the core.
