We report the experimental implementation of a wireless transmission system with a 146-GHz carrier frequency which is generated by optical heterodyning the two modes from a monolithically integrate
Quantum Well Infrared Photodetector (QWIP) usually suffer from a too moderate quantum efficiency and too large dark current which is often announced as crippling for low flux applications.
We demonstrated a 15-spatial-mode photonic lantern fabricated with the ultrafast laser inscription technique. The fabricated device showed
We have developed 920-nm pump modules for Yb-doped fiber amplifiers. The pump laser utilizes a single layer of In(AlGa)As/GaAs quantum-dot material as active region.
First long haul full C-band 32Gbaud PDM 16-QAM transmission experiment is demonstrated.
We demonstrate a record distance with N * 43 Gb/s RZ-DQPSK modulated channels.
Reported is the first demonstration of the performance and properties of a singlemode Fabry-Perot laser processed from InAs/InP(311)B quantum dot material, which gives emission at 1.516 mu m under
1550 nm AlGaInAs DFB lasers and PIN receptors were developed for analog transmission up to 20 GHz. Over 20 GHz bandwidth are measured for both laser and detector.
This work reports the optimization of the design 1.55μm QDashes directly modulated lasers.
High speed transmissions up to 20Gb/s are reported using 1.55µm InP-based Quantum Dashes distributed feedback lasers.
