Abstract
AbstractA new system of a highly tunable visible laser source using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. Several Gaussian pulses with different center wavelengths are investigated using the designed system. The obtained results have shown that the very fine tuning wavelengths covering the visible laser wavelengths can be generated. With the very sharp peak and broad spectrum, for instance, when the Gaussian input pulse with the center wavelength at 700 nm, the spectral width of 20 pm is obtained. The interesting aspect is that the increasing in microscopic recording pen (i.e. peak) can be used to increase the imaging resolution, where the multicolor imaging, especially for multicolor bio‐cell microscopy is the target. © 2009 Wiley Periodicals, Inc.
