Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Published in the journal Nature Communications, the ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

Abstract: A high-power S-band klystron based RF system has been developed at the Raja Ramanna Centre for Advanced Technology (RRCAT), Indore, to meet the RF power requirements of the infrared ...

Abstract: We present a method to achieve vector modulation of lightwave using an electroabsorption modulator intregrated laser. The laser section is used for direct phase modulation followed by an ...
