| 요약 | In the age of Big Data, the demand for higher capacity hard disk drives (HDDs) is ever increasing. To enable higher recording densities, heat assisted magnetic recording (HAMR) is being investigated as a promising approach. This technology uses |
| 요약 | We begin our study by fabricating a Fabry-Perot GaAs/AlGaAs quantum dot bar laser. To optimize our laser, we first address the issue of power fluctuation as it directly affects the quality of the data written in HAMR. We minimize power fluctuati |
| 요약 | We continue our optimization by examining what is needed to allow the laser to operate in continuous-wave (CW) rather than pulsed to enable continuous data writing. Based on the pump duty cycle and thermal resistance of our structure, we examine |
| 요약 | The final study examines the coupling efficiency of the waveguide-resonator-NFT system using Si3N4 core/SiO2 cladding. We achieve critical coupling between a rectangular waveguide and a disk resonator using a coupling distance of 100 nm, disk ra |
| 요약 | In summary, this work presents an analysis of a complete HAMR light delivery system design and supports key aspects of that design with experimental confirmation of design assumptions. Specifically, the design includes a mode stabilized laser op |
