Article Synopsis
- The study examined an educational program aimed at improving knowledge, attitudes, depression levels, and quality of life among patients with epilepsy (PWE).
- Results showed that after the program, patients significantly improved their knowledge and attitudes towards epilepsy, outperforming medical students and residents in those areas.
- However, while the benefits lasted for six months for knowledge and attitudes, patients with depression required additional support to maintain improvements in their attitudes.
For large-area ion-implanted vertical-cavity surface-emitting lasers (VCSELs), side emission from the edges of a chip disturbs the laser emission of a VCSEL mode, and suppression of it is fundamental. In this paper, we present results of a numerical investigation of the side emission from large-area VCSELs. We have modeled a VCSEL structure by an infinitely broad layer structure with mirror loss at the edge surfaces.

A continuous-wave output power of over 380 mW and the power density of 4.9 kW/cm have been achieved at 15 °C from the 100-μm-diameter aperture, which is the highest output characteristic ever reported for an ion implanted VCSEL.
