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 11):
The discrete wavelength tunable laser of  claim 3 , further comprising additional SOAs and additional AWGs such that the tunable laser includes:\n a plurality of SOAs and a plurality 1\u00d7M AWGs, the output of each SOA providing an input to a 1\u00d7M AWG; a plurality M of output waveguides optically coupled to each 1\u00d7M AWG, each of the M output waveguides optically coupled to a respective one of the M output of that 1\u00d7M AWG, wherein each of the M outputs of each 1\u00d7M AWG includes a respective one of the one or more tunable DBRs.
