    摘要: An energy assisted magnetic recording (EAMR) disk drive comprises a suspension and a slider having a back side, a laser-facing surface, and an air-bearing surface (ABS) opposite the back side. The slider is mounted to the suspension on the back side. The disk drive further comprises an EAMR transducer coupled with the slider, a portion of the EAMR transducer residing in proximity to the ABS and on the laser-facing surface of the slider. The disk drive further comprises a laser coupled with the suspension and having a light emitting surface facing the laser-facing surface of the slider. The laser has an optic axis substantially parallel to the suspension. The laser provides energy substantially along the optic axis and is optically coupled with the EAMR transducer via free space. The EAMR transducer receives the energy from the laser and writes to the media using the energy.

    摘要: A magnetic head comprising a waveguide coupler for coupling incident electromagnetic (EM) radiation into a waveguide is disclosed. The waveguide coupler includes a bottom clad layer and a waveguide core layer formed above the bottom clad layer. An interface between the bottom clad layer and the waveguide core layer includes a first grating having a first period and a first etch depth, which are configured to couple a first portion of the incident EM radiation into the waveguide core layer. The waveguide coupler can further comprise a top clad layer formed above the waveguide core layer. An interface between the waveguide core layer and the top clad layer includes a second grating having a second period and a second etch depth. The second period and the second etch depth are configured to couple a second portion of the incident EM radiation into the waveguide core layer.

    摘要: A tunable filter may be utilized to successively tune to different wavelengths. As each wavelength of the wavelength division multiplexed signal is extracted, it may be successively power monitored. Thus, power monitoring may done without requiring separate power monitors for each channel. This results in considerable advantages in some embodiments, including reduced size, reduced complexities in fabrication, and reduced yield issues in some embodiments.
