Abstract
An optical fiber array block includes at least one optical waveguide having an optical fiber zone, and an optical device. An optical signal leakage window is formed at the optical waveguide, and the optical device corresponds to the optical signal leakage window. If the optical signal leakage window is formed at an optical fiber comprising a core and a clad layer, the clad layer is partially removed or is partially connected to the core by means of an ion implantation technique.
Claims22
An optical fiber array block, the block comprising:
- an optical waveguide including a plurality of optical fibers, each optical fiber being settled in grooves formed on a board and including, a core, a clad layer and one or more leakage windows;
- one or more optical devices arranged corresponding to the one or more leakage windows;
- an intermediate panel interposed between a substrate where the optical devices are provided and the board;
- and
- wherein the intermediate panel has one or more guiding hole penetrating the intermediate panel to lead optical signals emitted from the leakage windows to the optical devices.
