then use Bragg selectivity to record subsequent images at the same location to achive storage densities as high as several Tbit/square inch. Starting while at a Silicon Valley startup, Siros ...

or the combined storage capacity of about 15,000 DVDs. Optical discs, such as DVDs and Blu-ray discs, are durable and inexpensive. A standard single-layer Blu-ray disc can store 25 gigabytes.

However, their limited data storage capacity has been a constraint in an era defined by exponential data growth. Until now, optical disks have predominantly relied on a single layer of data ...

enables these Sanyo blue-violet laser diodes to offer the extra performance required for advanced DVD and optical data-storage applications. The three 405-nm-wavelength Sanyo laser diodes are ...

The layer structure of these materials allows them to possess unique electronic, optical, and mechanical properties, which makes them interesting for a wide range of applications, from nanoelectronics ...
