Abstract: A folded lasing cavity comprises at least one bend. The folded lasing cavity is disposed on and configured to emit light along a substrate-parallel plane. An etched facet is on an emitting end of the folded lasing cavity and an etched mirror is on another end of the folding lasing cavity. An etched shaping mirror redirects light received from the etched facet in a direction normal to the substrate-parallel plane.

Abstract: A wafer is formed having a plurality of laser-to-slider submount features on a first surface. An etching process is used to form scribe lines between the submounts on the first surface of the wafer. The wafer is separated at the scribe lines to form the submounts.
Abstract translation: 在第一表面上形成具有多个激光到滑动器底座特征的晶片。 蚀刻工艺用于在晶片的第一表面上的底座之间形成划线。 晶片在划线处分离以形成底座。

Abstract: A recording head includes a substrate, a read transducer, a waveguide core, and a near-field transducer at an end of the waveguide core proximate a media-facing surface. The recording head includes a magnetic write pole and coil. A laser diode unit with one or more non-self-supporting layers of crystalline material region is transfer printed between layers of the recording head.

Abstract: A laser is configured to emit light along a substrate-parallel plane along a first surface of the laser. An etched facet is on an emitting end of a lasing cavity and an etched mirror is on another end of the lasing cavity. An etched shaping mirror redirects light received from the etched facet in a direction normal to the substrate-parallel plane. A slider comprises an optical input coupler configured to couple the light from the laser into a waveguide of the slider. At least one protrusion is disposed on the laser and at least one recession is disposed on the slider, the at least one protrusion and the at least one recession configured to align the laser with the slider to allow the light to be coupled into the optical input coupler.

Abstract: An apparatus comprises a slider configured to facilitate heat assisted magnetic recording and a submount affixed to the slider. A laser unit is affixed to the submount and comprises a laser operable in a non-lasing state and a lasing state. A heater is embedded in the laser unit or the submount. The heater is configured to generate preheat for heating the laser during the non-lasing state and to generate steering heat for heating the laser during the lasing state.
