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 ...
Illustration of a Raman-suppressed, X-cut thin film lithium niobate racetrack microresonator used for microcomb generation. Harvard researchers have demonstrated a special type of optical 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 ...
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 ...
