Embodiment Construction
[0019] Below by specific embodiment and in conjunction with accompanying drawing, the present invention is described in detail:
[0020] figure 1 It is a schematic diagram of an embodiment of the V-shaped groove substrate used for the output end of the waveguide chip after being made into an optical fiber array disclosed by the present invention. Such as figure 1 As shown, the V-shaped groove substrate 10 includes a substrate body 1 and a plurality of V-shaped grooves 2 located thereon, and the V-shaped groove 2 includes an input section 20 , a connecting section 21 and an output section 22 . The end surface of the substrate body 1 is perpendicular to the surface thereof, the V-shaped grooves 2 are arranged in parallel and the intervals between the V-shaped grooves are equal. The input section 20 of the V-shaped groove 2 is arranged in a straight line and forms an angle α with the normal line of the end surface of the substrate body 1 . In some embodiments, the deflection...
