High-Power and Low Phase Noise Full-band Tunable LD for Coherent Applications
Semiconductor lasers Lasers tunable
2015/6/10
High output power and low noise performances of CSG-DR-LD have been investigated. Kink-free fiber output power > 60mW over C-band with high SMSR have been demonstrated. Measured phase noise is lower t...
Narrow Spectral Linewidth Full Band Tunable Laser Based on Waveguide Ring Resonators with Low Power Consumption
Lasers tunable Silica Waveguides Semiconductor optical amplifiers
2015/6/8
We have developed a widely tunable laser source that uses triple ring resonators with narrow spectral linewidth. A spectral linewidth of less than 100 kHz is obtained for all wavelength channels acros...
Widely Wavelength Flexible Operation of All-Optical Regeneration in RZ-OOK Signals Using Gain-Band Tunable Raman Amplifier
Widely Wavelength All-Optical Regeneration RZ-OOK Signals Tunable Raman Amplifier
2015/7/17
We demonstrate operating wavelength flexible all-optical signal regeneration with 80 nm wavelength range by simply controlling the pump wavelength of Raman amplifier and the passband of broadened sign...
