Physicists take big step in nanolaser design

Lasers are widely used in household appliances, medicine, industry, telecommunications and more. Several years ago, scientists introduced nanolasers. Their design is similar to that of the conventional semiconductor lasers ...

Advances in lasers get to the long and short of it

Since lasers were first developed, the demand for more adaptable lasers has only increased. Chiral nematic liquid crystals (CLCs) are an emerging class of lasing devices that are poised to shape how lasers are used in the ...

GaN-based transistor blocking voltage exceeds 1kV

Research reported in Applied Physics Express (APEX) describes the development of 'vertically orientated' GaN-based transistors with blocking voltages exceeding 1kV. These findings are important for the application of nitride ...

Why doesn't work always offer a safe escape route from poverty?

On Monday, British lawmakers will vote on a welfare bill which reflects a widely accepted idea that paid employment provides an important route out of poverty for people of working age. In fact, the proposals make it clear ...
