In this article, a new architecture for broad-area laser diode on glass platform is proposed. It is composed of a planar mode converter made by ion-exchange on glass and a Fiber Bragg Grating and provides a single-mode and wavelength selective optical feedback in the multimode pump laser. The spectral locking of the laser diode is experimentally demonstrated with a side mode suppression ratio superior to 25 dB for an injection current inferior to 1 A.
