Abstract
An arrangement for coupling an optical fiber (1) to a waveguide (8) which forms part of an integrated optical device (4) uses a block (3) with a narrow slot (2) to receive the bared fiber end. On top of this block is a retaining block (6), of transparent material such as glass. These are held together by epoxy, and the front face rendered smooth. A polishing block (10) is glued to the edge of the IO device (4), and the end of the block is polished. Then the fiber and the guide on the IO device are brought together in proper alignment and secured together.
