Characterization of Semiconductor-Laser Phase Noise with Digital Coherent Receivers
Characterization Semiconductor-Laser Phase Noise Digital Coherent Receivers
2011/5/20
We develop a method of characterizing semiconductor-laser phase noise using a digital coherent receiver. The field spectrum, FM-noise spectrum, and phase-error variance can completely describe phase-n...
Self-Coherent Optical Transmission Using a Narrow Linewidth Tunable Slotted Fabry-Perot Laser
Coherent communication Semiconductor lasers
2010/6/4
A narrow linewidth slotted Fabry-Perot laser has been employed in a self-coherent optical transmission system. A comparison of the system performance of the tunable slotted laser with a SG-DBR laser h...
Development of Coherent Anti-Stokes Raman Scattering Microscopy
Nonlinear spectroscopy Ultra-fast laser Raman spectroscopy microscopy
2009/6/12
New multiphoton microscopy using CARS (Coherent Anti-Stokes Raman Scattering) spectroscopy is described. In CARS microscopy, the image of molecular vibration that is sensitive to the molecular spices ...
