Optical amplification prior to photon-to-electron conversion improves detection sensitivity in spectroscopic and imaging applications. Here we report the first experimental demonstration of Raman amplification in a single-mode fiber at wavelengths near 800 nm. This approach can potentially enable fast real-time optical sensing and imaging in the wavelength band that benefits from both low water absorption and the availability of high-power Ti:Sapphire lasers.

    The lifetime of two-photon generated carriers has been established as the critical parameter that determines the performance of silicon Raman lasers and amplifiers since it determines the optical loss. Here, we investigate the intensity dependence of the carrier lifetime in the case where the...

    We investigate the effect of mid-infrared (MIR) pumping on the transport properties of GaAs/(Al,Ga)As terahertz (THz) quantum lasers (TQLs), which rely on quantum coherence effects of intersubband transitions. Aiming at THz lasing at elevated temperatures, we extend the concept of THz gain with...
