High-Power,Low-Noise Slab-Coupled Optical Waveguide (SCOW) Amplifiers and Lasers
Semiconductor optical amplifiers Semiconductor lasers Mode-locked lasers
2011/5/22
We review the development of a Watt-level semiconductor quantum-well gain medium based on the slab-coupled optical waveguide (SCOW) concept. Devices realized in the 1.5-m-wavelength region inc...
Tuning Methods for Uncooled Low-Cost Tunable Lasers in WDM-PON
Tuning Methods Uncooled Low-Cost Tunable Lasers WDM-PON
2011/5/18
This paper investigates tuning of uncooled low-cost lasers without an integrated wave locker via a shared, centralized wave locker in a WDM-PON context.
Compact, Low Power and Low Threshold Electrically Pumped Micro Disc Lasers for 20Gb/s Non Return to Zero All Optical Wavelength Conversion
Wavelength conversion devices All-optical devices
2010/6/8
Using a 7.5μm wide InP Micro-Disc-Laser, with a very low ~100μA threshold current, heterogeneously integrated on top of Silicon on Insulator substrate, all optical NRZ wavelength conversion at speeds ...
Bandwidth Enhancement of Distributed Reflector Lasers at Low Bias Current by Optical Injection Locking
Lasers distributed-feedback Lasers injection-locked Quantum-well wire and -dot devices
2010/6/4
By optical-injection-locking, the bandwidth enhancement of Distributed-Reflector lasers with quantum-wire-like active regions was demonstrated. The bandwidth was increased to >15-GHz at a 5-mA bias, w...
16-channelx100-GHz Monolithically Integrated O-CDMA Transmitter with SPECTS Encoder and seven 10-GHz Mode-Locked Lasers
Photonic integrated circuits Networks
2010/6/4
We demonstrate a fully-integrated O-CDMA transmitter by monolithically integrating 7 colliding-pulse mode-locked lasers with two arrayed waveguide gratings and 16 phase modulators in InP technology.
