Abstract
A method of manufacturing a tuneable laser assembly including a substrate having formed thereon a plurality of tuneable lasers including Multi Quantum Well (MQW) active sections as well as distributed Bragg reflector (DBR) tuning sections. The lasers have respective emission wavelengths and tuning ranges such that the laser assembly can be tuned over a quasi-continuous predetermined wavelength range. The assembly also includes a plurality of passive waveguides coupled to the lasers to receive therefrom the respective emission wavelengths as well as an optical coupler coupled to the waveguides to receive via the waveguides the emissions wavelengths from the lasers. A Multi Quantum Well (MQW) amplifier coupled to the coupler amplifies the emission wavelengths coupled via the optical coupler. The method includes the steps of:
