Effectiveness of a program director for osteopathic medical education to support osteopathic recognition at a training site with multiple programs.

Context: With the advent of the Single Accreditation System (SAS) within the Accreditation Council for Graduate Medical Education (ACGME), few programs have achieved Osteopathic Recognition (OR) status to date. OR is an accreditation that graduate medical education (GME) programs can achieve to distinctly acknowledge the additional focus on osteopathic training. There is an effort by national osteopathic organizations to determine barriers for programs to achieve OR and what innovative methods might help overcome them.

Unidirectional hybrid diode laser through the integration of a hook-shaped traveling-wave semiconductor optical amplifier and Taiji ring resonator.

We demonstrate a unidirectional ring diode laser based on hybrid integration of a hook-shaped traveling-wave semiconductor optical amplifier (SOA) and a Taiji ring resonator. The additional crossover bending waveguide inside the silicon nitride Taiji ring introduces a non-reciprocal loss in the laser cavity while the gain is provided by a multiple depth etched hook-shaped SOA. We present the detailed design flow for both active and passive components of the unidirectional hybrid diode laser.
