Paper Abstract

The fabrication of integrated ring semiconductor lasers has been simplified by embedding the etched rib waveguide structures in polyimide and overcoating with a gold bonding layer. Structures defined by optical lithography lased successfully, while e-beam defined devices with very narrow rib structures were optically lossy, resulting in increased threshold current and evidence of second quantised state operation.
