An all semiconductor swept laser source relying on state filling in quantum dot lasers is discussed. The use of a multi-contact laser operating at the saturated gain of the ground state allows a new type of swept laser source to be realised. Analysis of the prototype device is made and design rules for optimised operation are discussed.
