POLYMERIC PHOTONIC CRYSTALS WITH CO-CONTINUOUS PHASES

摘要

AN OPTICAL ELEMENT(100,210,310,400,440,450,460,600,610,620,700,830,1200,1310) IS FORMED BY CO-EXTRUDING TO HAVE AN ARRANGEMENT OF POLYMER SCATTERING FIBERS(104,304,404) WITHIN A POLYMER MATRIX(102,702). THE SCATTERING FIBERS LIE SUBSTANTIALLY PARALLEL TO A FIRST AXIS. THE SCATTERING FIBERS(104,304,404) ARE ARRANGED AT POSITIONS ACROSS THE CROSS-SECTION OF THE POLYMER MATRIX(102,702) TO SCATTER LIGHT TRANSVERSELY INCIDENT ON THE OPTICAL ELEMENT IN A DIRECTION SUBSTANTIALLY ORTHOGONAL TO THE FIRST AXIS. THE POSITIONS OF THE SCATTERING FIBERS(104,304,404) ACROSS THE CROSS-SECTION OF THE OPTICAL ELEMENT MAY BE SELECTED SO AS TO FORM A TWO-DIMENSIONAL PHOTONIC CRYSTAL STRUCTURE FOR LIGHT TRANSVERSELY INCIDENT ON THE OPTICAL ELEMENT.
