OPTICAL FIBER WITH LENS, METHOD FOR MACHINING THE SAME, AND METHOD FOR ASSEMBLING OPTICAL SEMICONDUCTOR DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To markedly shorten an assembling time of an optical semiconductor device. SOLUTION: In the optical fiber 10 with lens, obtained by removing the coating 15 of the tip of the optical fiber and forming a pair of inclined planes 11 which are symmetrical with respect to the core axis 12 of the optical fiber, a direction identifying part 14 is formed on the coating 15 of the optical fiber is formed in accordance with the direction of the inclined planes 11.
