Abstract
Wavelength (frequency) tuning, coverage, and linewidth reduction characteristics of a visible laser diode (LD) operating near 656 nm at room temperature were investigated by using optical feedback from Littrow-type grating (LG). Frequency tuning coefficients on the grating angle, LD temperature, and injection current were found to be 1 THz/degree, 32.39 GHz/K, and 6.15 GHz/mA, respectively, using a InGaAsP visible laser diode.
