摘要

PCT No. PCT/DE96/01256 Sec. 371 Date Jan. 7, 1998 Sec. 102(e) Date Jan. 7, 1998 PCT Filed Jul. 11, 1996 PCT Pub. No. WO97/04340 PCT Pub. Date Feb. 6, 1997An optical structure which is suitable as an optical waveguide or cavity comprises a carrier having a lattice structure with a photonic band gap and a defect region. The lattice structure comprises pores which have constriction and are arranged in a periodic grid pattern which is disturbed in the defect region. The optical structure can be produced by the electrochemical etching of silicon.
