Abstract:
A discrete wavelength tunable laser having an optical cavity which comprises: a reflective semiconductor optical amplifier (SOA); a demultiplexer (Demux) having a single input and a plurality of outputs, the Demux configured to receive the output of the SOA and to produce a plurality of fixed spectral passbands within the gain bandwidth of the SOA; one or more tunable distributed Bragg reflector(s) (DBR(s)) arranged to receive the outputs of the Demux, each tunable DBR configured to select a reflective spectral band within the gain bandwidth of the SOA upon application of a bias current; wherein the SOA forms the back end mirror of the optical cavity; the one or more tunable DBRs form the front end mirror of the optical cavity; and wherein the lasing channel of the discrete wavelength tunable laser is chosen by the overlap of the selected reflective spectral band of one of the one or more tunable DBRs with a fixed spectral passband of the Demux.

Claim (Index 4):
The discrete wavelength tunable laser of  claim 3 , wherein:\n the AWG is a 1\u00d7N AWG which splits the spectral output of the SOA into an integer number N of respective output waveguides; and wherein the discrete wavelength tunable laser includes a further AWG which acts as a multiplexer to multiplex the signals from the N respective output waveguides to produce a common output of the laser.
