| Research Abstract |
Compact and low-cost semiconductor laser-induced fluorescence detection systems for simultaneous multiple detection can be realized by combination of grating coupled surface-emitting lasers and microfluidic structures. We designed and fabricated red and near-infrared distributed Bragg reflector lasers integrated with the phase-shifted grating coupler for multisport focusing. 5×5 and 7×7 spot arrays were obtained from the red integrated laser. The grating coupler designed for near-infrared light also emitted a multispot array. By combination of the semiconductor lasers, dual-band filter and fluorescence dyes for red and near-infrared light, preliminary test of two-wavelength semiconductor laser-induced fluorescence detection was demonstrated.
