Confining light for use in nanophotonic devices

`There is a strong drive to make smaller and smaller devices,` Hui Cao tells PhysOrg.com. `However, there are limitations to what we can do. We want faster devices than what we can get from electronics, so we are looking to photonics. Unfortunately, photonics, while having the potential to be much faster, are larger in size. Devices using electrons are smaller, on the... [via Physorg]
