Abstract:The spatiotemporal dynamics of optical losses and carrier density in a heterostructure of a semiconductor laser with a segmented contact were studied using an optical probe technique based on the coupling of probe radiation with a wavelength of 1560 nm into a semiconductor laser chip under investigation based on an AlGaAs/ InGaAs/ GaAs heterostructure and emitting at a wavelength of 1010 nm. It has been shown that the use of a probe beam with a wavelength of 1560 nm makes it possible to ensure the sensitivity … Show more
