Abstract: We have numerically studied single-frequency gain-switched $\mathbf{2}-\boldsymbol{\mu} \mathbf{m}$ thulium doped fiber laser oscillator with cm-level long cavity length. The peak output ...

Abstract: A monolithic silicon-based optoelectronic integrated system consisting of quantum dot microdisk lasers, coupled waveguides, and photodetectors, is demonstrated. The feasibility of this ...
