1.55 µm wavelength band photonic crystal surface emitting laser with n-side photonic crystal and operation at up to 85 °C.

We describe the structure, fabrication, and measured performance of a 1543 nm wavelength photonic crystal surface emitting laser. An asymmetric double lattice design was used to achieve single mode lasing with side mode suppression ratios >40 dB. The photonic crystal was formed using encapsulated air holes in an n-doped InGaAsP layer with an InGaAlAs active layer then grown above it.

'Internet is easy if you know how to use it': Doing online research with people with learning disabilities during the COVID-19 pandemic.

Background: The coronavirus disease 2019 pandemic changed the way we live, work, interact and do research. Many activities moved online, and digital inclusion became an urgent issue for researchers working with people with learning disabilities and other groups at risk of exclusion. This has generated new questions about how we conduct research and what it means to go into 'the field'.

Over 65% Sunlight Absorption in a 1 μm Si Slab with Hyperuniform Texture.

Thin, flexible, and invisible solar cells will be a ubiquitous technology in the near future. Ultrathin crystalline silicon (c-Si) cells capitalize on the success of bulk silicon cells while being lightweight and mechanically flexible, but suffer from poor absorption and efficiency. Here we present a new family of surface texturing, based on correlated disordered hyperuniform patterns, capable of efficiently coupling the incident spectrum into the silicon slab optical modes.

Development and Initial Validation of the Attitudes Towards Older Adult Sexuality in Long-term Care Scale (AOASLC).

In long-term care facilities where older adults may reside, negative attitudes about later life sexuality can result in restrictive facility policies and staff behaviors that suppress residents' rights to sexual expression. No assessment instrument specifically focuses on the sexual behaviors of long-term care residents and existing measures of attitudes toward older adult sexuality do not include sexual expression in long term care, nor do they assess a full range of sexual behaviors. We developed the Attitudes toward Older Adult Sexuality in Long-term Care Scale (AOASLC).
