Abstract: | It is shown that superluminescent diodes rank below laser diodes in energy characteristics, but they have a wider emission
spectrum and lower noise level. The amplitude-frequency and noise characteristics of the laser diode correlate with each other,
whereas there is no such correlation for the superluminescent diode. The photon density distribution along the active area
is more homogeneous for the laser diode than for the superluminescent one.
