Method for moulding optical waveguides comprises injecting an optically transparent material such as an epoxy or polyimide into a mould to form a first optical portion (230), support apparatus (206) and end portions (231). By using grooves (301) indented into the end portions (3131, 314, 316), they may be broken off the optical portions (307, 308) on completion of the final cladding process. A second mould (400) is used to make a unitary cladding for the optical portions (303, 3037, 308, 309), suspended in and held by the mould (400) by injecting a selected moulding composition to surround and adhere to them. The waveguide support structure (206) and associated end portions (231) are removed from the mould (400) and the support structure (206) and end portions (231) removed from the waveguide by breaking, cleavage or sawing. |
