This work demonstrates that the relative intensity noise of Ge-based epitaxial InAs quantum dot lasers are weakly sensitive to the temperature, while it is more sensitive to the optical feedback at higher bias currents.

We demonstrate a continuous-wave Pr3+:YLF laser pumped by blue laser diodes, and obtain the output power of 6.7 and 3.7 W at 640 and 607 nm, respectively. The Pr3+:YLF laser is extended to passive Q-switching by utilizing a Co2+: MgAl2O4 spinel saturable absorber and its intracavity second harmonic generation at DUV.

Metasurfaces have been designed for plane waves or point emitters with precise positions, but generally fail to control emission from random light emitters such as LEDs. We demonstrate a method that resolves this problem.

We report on a tunable 2 μm optical vortex laser source formed of a periodically poled stoichiometric lithium tantalite (PPSLT) optical parametric oscillator with a singly-resonant cavity configuration. A milli-joule level vortex output was generated at a low lasing threshold (1.2 mJ), with its wavelength being tuned within a range of 1.85-2.03 μm.

We experimentally demonstrate real-time 4⨯28-Gb/s transmission over 110 km single mode fiber. Chromatic dispersion pre-compensation and post-compensation are achieved by dispersion compensation fiber and wavelength selective switch, which is also used for wavelength division multiplexing.
