摘要 | The present invention generally relates to a HAMR head having not only a tapered core for the SSC, but additionally a secondary confinement material in the cladding surrounding the core taper. The secondary confinement material prevents diverging light from the laser diode from spreading so that the light is coupled into the core of the SSC. The secondary confinement material is a symmetric structure that surrounds the core of the SSC on all sides so that high conversion efficiency is achieved for short taper lengths. |
其他摘要 | 本发明一般涉及一种HAMR头,其不仅具有用于SSC的锥形芯,而且还包括围绕芯锥的包层中的第二限制材料。次级限制材料防止来自激光二极管的发散光散射,使得光耦合到SSC的核心中。次级限制材料是对称结构,其在所有侧面围绕SSC的芯部,从而对于短锥形长度实现高转换效率。 |
主权项 | A heat assisted magnetic recording device, comprising:a spot size converter, wherein the spot size converter includes: a first cladding; a secondary confinement material disposed on the first cladding; a secondary cladding disposed on the secondary confinement material; and a core disposed within the secondary confinement material such that the core is spaced from both the first cladding and the second cladding; a waveguide coupled to the spot size converter; and a near field transducer coupled to the waveguide. |
