Ion-Exchanged glass DFB Lasers for DWDM

Nowadays, optical telecommunication systems require an increasing bit-rate. Fot this reason, Dense Wavelength Division Multiplexing (DWDM) systems are currently under development. They need optical sources with narrow and stable emission spectrum in the C band, which should also integrate several emission wavelengths. Glass waveguide lasers enable both the sharp linewidth of optical fiber lasers and the integration possibilities of semiconductor lasers. In this paper, the realization of ion-exchanged waveguide DFB lasers on glass substrates is presented.
