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 ...
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 ...
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...
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 ...
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 ...
