it can also be seen that the plasmon generator abuts the pole tip 900 of the write pole which is a part of the write element that has been shown as 31 in fig1 b referring next to fig7 there is shown a front schematic view of a tilted centerline 550 of a waveguide 510 and an adjacent plasmon generator 700 that is also tilted relative to the waveguide as shown by its centerline 770 referring next to fig8 there is shown a front schematic view of a straight waveguide 500 with an adjacent tilted plasmon generator 700 as shown by its tilted centerline 770 referring now to fig9 a there is shown schematically another approach to eliminate back reflections into a laser diode cavity in this approach the abs end surface 57 of the waveguide see detail in fig9 b is tilted relative to the abs surface 160 of the slider but at the back end surface 152 of the slider the surface 52 of the waveguide is not tilted since the centerline 550 of the waveguide is perpendicular to the abs of the slider the light ray 1 of the downward propagating laser light within the waveguide reflects off the tilted end surface of the waveguide as light ray 2 and is thereafter refracted out of the waveguide as indicated by the arrows representing light ray 3 in fig9 b light ray 3 will.
