Summary :

It is reported firstly that spatial filtering of laser beam by a receiving optical system such as a finite-aperture detector causes harmonic distortions of a directly modulated semiconductor laser diode when the beam irradiance is reflected partially at the submount. The theory based on geometrical optics for interference of directly emerging light and reflected light is developed and the numerical results are presented for a variety of laser structures and FM-modulation parameters.
