Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a new method for obtaining high-power short optical pulses without trailing pulses from an actively mode-locked LD.A part of the output is reflected back into the LD with the orthogonal polarization and the appropriate time delay.The dynamics of the LD was numerically analyzed using traveling-wave rate equations.We show that trailing pulses caused by both the excess gain and the residual reflection at an LD facet are suppressed.We also show experimental results using 1.55μm InGaAsP LD.
