摘要：
In one embodiment, a magnetic recording head includes a spot size converter having a tapered portion, the tapered portion having at least one of a width and thickness that increases in a direction towards an air bearing surface; a waveguide surrounding the spot size converter, the waveguide having a refractive index that is lower than a refractive index of the spot size converter; and cladding adjacent the waveguide, the cladding having a refractive index that is lower than the refractive index of the waveguide. Additional systems and heads are also disclosed.
