Developed using silicon MEMS technology, the SiRes SiTxxx fixed-frequency and SiT8002 programmable oscillator families generate frequencies between 1.000 to 125.000 MHz at optional frequency ...

A stable ‘frequency comb’ of photons with discrete colours has been generated on a microscale chip by removing copper contaminants from the circuit. The development of PICs was enabled by advances in ...

A silicon microresonator (left, SEM image) provides a parametric broadband source for frequency-entangled photon pairs 21 GHz apart to achieve frequency-encoded large-scale quantum networks. The ...

A new chip with hundreds of microscopic rings generated the first topological frequency comb. Credit: E. Edwards Scientists on the hunt for compact and robust sources of multicolored laser light have ...

In a paper published July 24 in the journal Nature Nanotechnology, a team of Caltech engineers reports building a metasurface patterned with miniscule tunable antennas capable of reflecting an ...

Capable of generating frequencies of 350 to 700 MHz within 0-10 Vdc of tuning, the V350ME01 voltage-controlled oscillator (VCO) registers a SSB phase noise performance of -100 dBc/Hz at 10ÊkHz offset ...

Scientists on the hunt for compact and robust sources of multicolored laser light have generated the first topological frequency comb. Their result, which relies on a small silicon nitride chip ...
