Abstract
In this paper, we propose an evaluation method for device parameters
of solid-state organic lasers. Using a self-written active (SWA) waveguide
technique, a Fabry–Pérot (FP)-type organic laser with a channel
waveguide structure was fabricated, in which the cavity length and the feedback
efficiency can be easily controlled. The lasing threshold of the fabricated
organic laser showed a monotonic decrease with increased cavity length. From
the experimental result, the optical net-gain coefficient and the loss coefficient
could be quantitatively evaluated. The evaluation method described here would
be an available means to estimate the performance of the laser device with
organic compounds.
