Mechanically tunable optofluidic distributed feedback dye laser

摘要

We demonstrated a continuously tunable optofluidic distributed feedback (DFB) dye laser on a monolithic poly(dimethylsiloxane) (PDMS) chip. We obtained /spl sim/60 nm tuning range by mechanically varying the grating period. Single-mode operation was maintained with <0.1 nm linewidth.
