Abstract
An integrated opto-electronic component includes an amplifying segment coupled to a tuning segment to provide a wavelength tunable laser oscillator function insensitive to the polarization of optical waves that it receives. The amplifying segment is designed to be insensitive to polarization. The tuning segment includes a Bragg grating and a waveguide dimensioned to procure transversely monomode laser emission with rectilinear polarization. Applications include wavelength converters and stabilized gain amplifiers, in particular for optical transmission.
