Optical hollow waveguide

Abstract

Abstract PURPOSE:To permit each member to curve or flex independently according to the force of curvature or flexure by fitting or joining long-sized split members mutually in a rectangularly sectioned shape without fixing them, and by covering the external circumference with an elastic body. CONSTITUTION:To form a hollow waveguide whose internal surface is polished into mirror one while its section is made rectangular, two long-sized split members 1 and 2 in rectangularly sectioned shapes are fitted or joined together opposite to each other without being fixed. In this case, the both are so fitted together that the external surfaces of the split member 2 are in skin contact with the internal surfaces of the split member 1, or that the internal and external flanks of the split members 1 and 2 are in skin contact alternately. Further, L-sectioned split members 3 and 4 are joined opposite to each other to form the rectangularly sectioned hollow waveguide. The obtained center optical waveguide is covered in lengthwise direction with an elastic body, such as rubber and plastics, so as to maintain the fitting and joining without any slide between members.
