Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should ...
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 ...
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 ...
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 ...
The electric field inside an integrated quadratic nonlinear resonator can have two signs: positive or negative. When two fields of opposite signs coexist, they connect through sharp transitions called ...
