<p><P>PROBLEM TO BE SOLVED: To provide an optical pulse multiplexing unit in which an optical pulse train having a high coupling efficiency is emitted and a pulse interval of the optical pulse train is arbitrarily set, an optical pulse generator using the optical pulse multiplexing unit, and an optical pulse multiplexing method. <P>SOLUTION: The optical pulse multiplexing unit has a half mirror 2 and N pieces of delay elements 311, 312 through 31N having refractive index n. Respective N pieces of delay elements are arranged on one side of the half mirror 2 from one end to the other end and have different thicknesses ofΔ, 2Δthrough 2<SP>N-1</SP>Δ, respectively, whereΔstands for the minimum thickness. Further the optical pulse multiplexing unit has mirrors 11 and 12 which are arranged in parallel to each other, the half mirror 2 is arranged in parallel to and in the vicinity of an intermediate position of the mirrors 11 and 12, and N pieces of delay elements are arranged between the mirror 11 and the half mirror 2. Each of the N pieces of delay elements is a parallel flat plate, and the delay elements are arranged so that the normal direction of the face of the parallel flat plate is at an angle different from the direction from one end of the half mirror 2 to the other end. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
