Stimulated Brillouin scattering is a fundamental interaction between light and travelling acoustic waves and arises primarily from electrostriction and photoelastic effects, with an interaction strength several orders of magnitude greater than that of other relevant non-linear optical processes. Here we report an experimental demonstration of Brillouin-scattering-induced transparency in a high-...

Hybrid storage architecture is one efficient method that can optimize the I/O performance, cost, and power consumption of storage systems. Thanks to the advances in semiconductor and optical storage technology, its application area is being expanded. It tries to store data to the most proper medium by considering I/O locality of the data. Data management between heterogeneous storage media is i...

The ability to integrate micro-optical elements with movable structures and microactuators has opened up many new opportunities for optical and optoelectronic systemsI2. It allows us to manipulate optical beams more effectively than conventional methods, and is scalable to large optical systems. Optical MEMS (MicroElectroMechanical Systems) have applications in display, sensing, and optical dat...

The ever-increasing demand for high data storage capacity has spurred research on development of innovative technologies and new storage materials. Conventional GByte optical discs (DVDs and Bluray) can be transformed into ultrahigh capacity storage media by encoding multi-level and multiplexed information within the three dimensional volume of a recording medium. However, in most cases the rec...

A micro objective lens with the numerical aperture (NA) of 0.65 and clear aperture of 1.1mm was designed, fabricated, and tested for the proposed blue-light small-form-factor optical pickup head system. It adopted the finite optical conjugation and could be produced by using the glass molding technique. The experimental results verify the optical performance near the diffraction-limited focus s...
