Researchers Develop Purely Optical Cloaking

Technologies for making things invisible is always interesting. There are active and passive technologies that have been tried for this. My earlier posting Mercedes uses LEDs to create invisible car showed and active technology that used camera + huge LED display to make invisibility effect. Yesterday I saw a new interesting passive one. Researchers Develop


Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in

Quantum Photonics News

Two interesting recent news related to quantum photonics: Quantum Photonics article tells that Researchers from Nanjing University, Beijing Institute of Aerospace Control Devices, and Southeast University, Nanjing, in China have demonstrated the creation of entangled photons and their manipulation on a single chip.  The researchers used lithium niobate (LN) as the material for the chip.

New camera science and technologies

There has been lately some interesting science new and product articles on special camera technologies: World’s Fastest Camera Takes 4.4 TRILLION Frames Per Second: Researchers in Japan have developed a motion picture camera that can take 4.4 trillion frames per second. The work was published in Nature Photonics. They call their technique “sequentially timed all-optical
