摘要: A laser-to-fiber coupler is constructed by an optical waveguide arranged between a semiconductor laser and transmitting fiber through which beam emanating from the transmitted in order to reduce amount of reflection fiber, injected into active layer laser. The made at least one core radius or numerical aperture (N.A.) smaller than those fiber.
