Lead-free FASnI3 laser amplifiers integrated in flexible waveguides
(Optica Publishing Group, 2022)
A FASnI3 lead-free perovskite is integrated in a flexible waveguide to demonstrate Amplified Spontaneous Emission. An extremely low threshold, 1 µJ/cm2, is observed together with the formation of narrow random lasing lines ...
Spatially resolved dual-comb sensing using a single electro-optic modulator
(Optica Publishing Group, 2022)
We present a dual-comb imaging system based on a single pseudo-randomly driven
electro-optic modulator. The result is a cost-efficient and robust fiber-based scheme that can be
employed to perform spatially resolved ...
25 Million Sensing Measurements Per Second Using Quasi-Integer Ratio Time-Expanded φOTDR
(Optica Publishing Group, 2022)
We demonstrate the detection of strain perturbations along a 500 m optical fiber with 2 cm spatial resolution and 1 kHz sampling frequency via quasi-integer-ratio time-expanded φOTDR, requiring less than 100 MHz photodetection ...
