Single-mode 1.52 μm InAs/InP quantum dot DFB lasers
Quantum devices Lasers distributed-feedback
2015/5/25
Single-mode InAs/InP quantum dot DFB lasers with side-mode suppression ratio greater than 62 dB are demonstrated, operating CW up to 80°C. Relative intensity noise was less than -153 dB/Hz from 1 MHz ...
10.3-Gb/s Operation over a Wide Temperature Range in 1.3-μm Quantum-dot DFB Lasers with High Modal Gain
Lasers distributed-feedback Quantum dot devices
2015/6/8
Temperature-stable 10.3-Gb/s operation was attained for 1.3-μm quantum-dot DFB lasers with high modal gain. Clearly-opened eye diagrams with the extinction ratio of over 5.2 dB were obtained from -40o...
Simultaneous ER Enhancement and Frequency Stabilization Scheme for Directly Modulated DFB Lasers
Fiber optics communications Fiber optics links subsystems
2015/6/4
A simultaneous extinction-ratio enhancement and frequency stabilization scheme is proposed for directly modulated DFB lasers at the optical line terminal to enhance signal quality and to stabilize opt...
Optical frequency synthesizer based on selectively injection-locked DFB lasers from a femtosecond fiber laser comb
Optical frequency synthesizer DFB lasers fiber laser comb
2015/8/4
We present an optical frequency synthesizer based on two DFB lasers that can be selectively injection-locked to a desired single mode among the femtosecond fiber laser comb components.
