A novel optical platform integrates a Sagnac‐based interferometer with a high‐brightness multiple‐plate continuum source to advance two‐dimensional electronic spectroscopy. The robust system delivers octave‐spanning, 3.7‐femtosecond pulses and achieves intrinsic attosecond‐level phase stability without active feedback.

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture
A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...

Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Vibration induced phase noise in Mach-Zehnder atom interferometers
International audienceThe high inertial sensitivity of atom interferometers has been used to build accelerometers and gyrometers but this sensitivity makes these interferometers very sensitive to the laboratory seismic noise. This seismic noise induces a
