  Prismatic 2.0 – Simulation software for scanning and high resolution transmission electron microscopy (STEM and HRTEM) 

  Mcbean, Patrick (2021)

  Scanning transmission electron microscopy (STEM), where a converged electron probe is scanned over a sample's surface and an imaging, diffraction, or spectroscopic signal is measured as a function of probe position, is an ...

  Thermoreflectance Imaging of Semiconductor lasers with a Numerical Thermal Model 

  Donegan, John; Mc Closkey, David (2021)

  High resolution surface temperature maps of a slotted surface grating laser operating at approx. 1550 nm are obtained by means of CCD-thermoreflectance imaging. The resolution is such that the temperature of the 2 μm ...

  Optical, thermal, and bit-writing analysis of a directly coupled plasmonic waveguide for heat-assisted magnetic recording 

  Donegan, John (2020)

  We investigate the energy conversion process and subsequent thermal and bit-writing performance of a plasmonic near-field transducer (NFT) under steady-state operation within heat-assisted magnetic recording (HAMR) devices. ...

  Spatially resolved self-heating and thermal impedance of laser diodes using CCD-TR imaging 

  Donegan, John; Mc Closkey, David (2021)

  The spatial distribution of the surface temperature of single and multi-section slotted semiconductor laser diodes with surface gratings is investigated experimentally with CCDthermoreflectance imaging. The lasers are ...

  1.3 μm wavelength tunable single-mode laser arrays based on slots 

  Donegan, John (2021)

  Two twelve-channel arrays based on surface-etched slot gratings, one with non-uniformly spaced slots and another with uniformly spaced slots are presented for laser operation in the O-band. A wavelength tuning range greater ...
