Patent ID: 7817698

Claim:
A microfluidic dye laser comprising: a pump light source configured to provide light having a pump light wavelength; an elastomer, said elastomer substantially optically transparent at said pump light wavelength and at a microfluidic dye laser wavelength; a microfluidic channel defined in said elastomer, said microfluidic channel configured as a single mode 3D waveguide, said microfluidic channel configured to accept a fluidic dye; and an optical grating formed in said single mode 3D waveguide to form a single mode optical cavity, wherein, when a fluidic dye having a higher refractive index than said channel and said optical grating is present in said single mode 3D waveguide, said single mode 3D waveguide is configured to provide a single mode microfluidic dye laser light as output at said microfluidic dye laser light wavelength in response to illumination with light from said pump light source at said pump light wavelength.
