Wavelength conversion by cavity-enhanced injection-locked four-wavemixing in a fiber-Bragg-grating coupled diode laser [PDF]
, 1998 Four-wave mixing (FWM) in a fiber-Bragg-grating (FBG) coupled semiconductor laser is investigated. We show that a large resonance enhancement of the FWM conversion efficiency can be obtained when the laser cavity is injection-locked by the converted ...

Major Accomplishments in 2009 on Slow Light
IEEE Photonics Journal, 2010 We present a brief overview of recent advances in the field of “slow light,” the field that studies means for controllably reducing the group velocity of light to values much smaller than its vacuum velocity, $c$.

Practical method for modelling the nonlinear behaviour of a travelling wave semiconductor optical amplifier [PDF]
, 1993 The authors present a simple model of a travelling wave semiconductor optical amplifier with an appreciable degree of saturation. The model uses a particular way of linearising the total carrier recombination R(N) to find useful expressions for the ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling
Advanced Engineering Materials, EarlyView.Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.
