Optical Slot-Waveguide Based Biochemical Sensors
Sensors, 2009 Slot-waveguides allow light to be guided and strongly confined inside a nanometer-scale region of low refractive index. Thus stronger light-analyte interaction can be obtained as compared to that achievable by a conventional waveguide, in which the ...
