Abstract: A continuously electronically tunable semiconductor laser has a lasing section, and first and second control sections separated from the lasing section by air gaps in a longitudinal arrangement. The longitudinal arrangement positions the lasing section between the two control sections, with the longitudinal arrangement corresponding to a lasing direction of the lasing section. The arrangement places longitudinal modes of the semiconductor laser in common with the longitudinal arrangement of the sections. Current is provided to each of the first and second control sections and the lasing section. Tuning is achieved by varying the current provided to at least one of the first control section, the second control section and the lasing section.
