In order to obtain good optical characteristics in the Ga N-based vertical-cavity surface-emitting laser(VCSEL), different kinds of Al Ga N electron blocking la
In this paper, we address the problem of blind denoising for laser detection and ranging equipment(Li DAR) based on estimating noise level from Li DAR pulse echo. We first provide rigorous statistical
Power-over-fiber technology provides several advantages for harsh industrial application and can potentially be widely used in electric power system. In this pa
This paper has demonstrated the resonance fluorescence enhancement of R6G when gold nanoparticles(Au NPs) deposited in the porous Si photonic crystal device. Bo
In this work, Pr3+ was introduced into Nd3+-doped tellurite glass with composition Te O2-Zn O-Na2 O-Nb2 O5 to achieve broadband near-infrared emission. A broadb
