The so-called optical activity of materials has been studied extensively since then, so it is perhaps surprising that there is anything new to discover. However, José Goulon of the European Synchrotr...
The JIF scheme was set up in 1998 by the UK government and the Wellcome Trust – the world’s largest biomedical research charity – to provide much-needed funding for university labora...
Although researchers have proposed a wide variety of explanations for sonoluminescence, they are in broad agreement that the oscillating bubbles reach very high temperatures. Until now, however, singl...
In a photonic crystal the periodic variation of the dielectric constant results in a range of ‘forbidden’ frequencies called a photonic bandgap (PBG). Electromagnetic waves with a ‘f...
Nothing can travel faster than light. Despite a recent raft of reports in the media, this statement is as true now as it ever was. Nonetheless, experiments over the past 20 years have been forcing us ...
Converting electrical signals into optical pulses is one of the speed ‘bottlenecks’ in current telecommunications systems. To reach high data speeds, a series of electro-optic devices call...
