Highly coherent lasers with spectral hyperpurity can further advance the fields of science and engineering. Especially, a light source with controllable frequency domain parameters can be adapted t…
The intrinsic spectrum that results from the coupling of spontaneous emission in a laser cavity can determine the energy concentration and coherence of lasers, which is crucial for optical high-pre…
An ultra-widely tunable acousto-optic add-drop filter is proposed and demonstrated based on the acoustically-induced polarization conversion of cladding-etched single-mode fiber, which covers wavel…
The complex impulse responses of two types of coupled 2-core fibers, with homogeneous and heterogeneous cores, were measured by using a measurement system based on linear optical sampling. The meas…
A simultaneous angle-of-arrival (AOA) and frequency measurement system based on microwave photonics is proposed and experimentally demonstrated. The measurement of the AOA and the frequency is real…
In this paper, the arrays consist of series-connected monochromatic light-emitting diodes (LEDs) are proposed as the transmitter and receiver to implement an LED-to-LED underwater wireless optical …
Regression analysis based methods have shown strong robustness and achieved great success in face recognition. In these methods, convex l1 -norm and nuclear norm are usually utilized to approximate…
As an important supplement to radio frequency (RF) communication in a crowded indoor environment, high-speed multi-user visible light communication (VLC) is a promising candidate for practical appl…
We propose and demonstrate an overall non-mechanical spectrally steered laser rangefinder using the dispersion-tuned swept laser (DTSL) and a passive diffractive element. The DTSL has no mechanical…
The fifth generation (5G) of mobile communications introduces improvements on many fronts when compared to its previous generations. Besides the performance enhancements and new advances in radio t…
