Abstract
The present invention relates to a solid-state blended polymer system that has the property of tunable lasing wavelength through adjusting the blending ratio. It can be used for health monitoring, environmental monitoring sensor and tissue imaging. Current materials do not have the broad tunable range; from blue to infra-red across the optical range. By using the same two polymers, it is possible to produce laser emitting blue to red colour. It simplifies the design, eases multi-wavelength laser sensor system integration and therefore, making the production cost-effective.
Claims15
A solid-state blended polymer lasing system with a lasing wavelength that is determined by a selected blending ratio of polymer compounds in said polymer lasing system, wherein the blended polymer lasing system comprises a blend of at least two polymer compounds comprising poly(9,9-dioctylfluorene) and poly(2-(2′,5′-bis(2″-ethylhexyloxy)phenyl)-1,4-phenylenevinylene).
A solid-state blended polymer lasing system with a lasing wavelength that is determined by a selected blending ratio of polymer compounds in the polymer lasing system, wherein the blended polymer lasing system comprises a blend of at least two polymer compounds comprising poly(2-(2′,5′-bis(2″-ethylhexyloxy)phenyl)-1,4-phenylenevinylene) and poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene) and further comprising a DFB feedback structure with a grating integrated therein to provide a lasing output.
