The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...
Optical frequency combs have revolutionized technologies such as atomic clocks, spectroscopy, and ultra-fast lasers by acting as precise bridges between optical and microwave frequencies. As the ...
Researchers at MIT have demonstrated a compact, fully integrated frequency combs source that uses a carefully crafted mirror to generate a stable frequency comb with very broad bandwidth. The mirror ...
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 ...
Forward-looking: Columbia University researchers have developed a compact photonics chip capable of producing dozens of laser wavelengths from a single high-power source, a breakthrough that could ...
