Fluidic dye lasers were first developed in 1966 and are still useful optical devices due in part to their wide bandwidth which makes large wavelength tunability and short pulse generation possible. More recently, miniaturization of fluidic dye lasers has emerged as a powerful option for integration of coherent light sources on a lab-on-a-chip device. Despite efforts by several groups, realization of room-temperature chip-based dye lasers with low threshold still remains a challenge. In this work, we introduce a new approach based on flowing a highly concentrated dye solution through a planar optical antenna. With our current design, we will be able to collect 99% of the spontaneously emitted photons [1,2] into the lasing mode of a cavity formed by an external mirror and the antenna. Based on our high collection efficiency, we expect to achieve a high coupling efficiency (β = 1) and low laser threshold.
