    摘要： Provided is a waveguide photodetector including: a first clad layer disposed on a substrate; a core layer disposed on the first clad layer and for absorbing predetermined light; a second clad layer disposed on the core layer; and at least one subsidiary layer inserted in the first clad layer and the second clad layer. In this structure, the photodetector has about the same spot size as that of an optical fiber or planar lightwave circuit (PLC), so that incident light can be absorbed without loss, and the photodetector can more efficiently combine with the optical fiber or PLC and operate even at high power.

    摘要： There are provided an apparatus for fixing a plastic sheet which fixes a plastic sheet to fabricate a nano pattern and a method of fabricating a nano pattern on a plastic sheet using the same. The apparatus for fixing a plastic sheet includes: a pair of planar metal guide rings interposingly fixing a plastic sheet from above and below, respectively; and a sheet fixing chuck including: a ring fixer sucking the pair of planar metal guide rings through a vacuum groove to be fixed thereto; and a sheet fixer having a plurality of vacuum pin holes formed therein, the vacuum pin holes sucking a bottom of the plastic sheet fixed by the planar metal guide rings. The apparatus allows fabrication of the nano pattern on the plastic sheet having less roughness than that of a semiconductor substrate or a glass substrate.
