There is Poisson slot noise generated by the single photon avalanche diode (SPAD) and Gaussian thermal noise generated by the transimpedance amplifier, respectively, if an analog SPAD detector is applied in the visible light communication (VLC) system. In this letter, for the long distance SPAD-based underwater VLC system, a fast blind multiple-symbol detection (MSD) algorithm is developed under the...
We demonstrate an octave spanning, 1.9–6.2 μm supercontinuum generation in a low loss silicon on a sapphire (SOS) nanowire. This establishes SOS as a promising new platform for integrated nonlinear photonics in the mid-IR.
We developed chalcogenide planar platform for mid-infrared applications. Careful choice of materials and control of fabrication are crucial for low-loss waveguide. The devices were demonstrated as chemical sensor and mid-infrared light source using super-continuum generation.
We have produced μ20mW of mid-infrared super continuum spanning from 1750nm to ≈8000nm spanning using a 1cm long chalcogenide waveguide pumped by a 21MHz train of 320fs pulses at 4μm.
We have produced a stable 10mW, mid-infrared supercontinuum spanning the full functional group band from 1750nm to >7000nm spanning using a 1cm long chalcogenide waveguide pumped by a 20MHz train of 320fs pulses at 4µm.
