In large-span space communication, the current bundle delivery mechanism using the Disruption-Tolerant Networks (DTN) technique confronts huge challenges such as high packet loss rate and huge latency ...

The waveguide modes have been calculated for the separated multiclad-layer stripe geometry laser recently described by Ishikawa et al. Our analysis includes coupling of the mode within the stripe to ...

We propose a vanadate crystal-based composite gain medium consisting of Tm3+ and Ho3+ ion-doped sections, which facilitates the direct use of common 800 nm diode lasers for a miniature 2.1 μm laser ...
