Solid-state organic laser using self-written active waveguide with in-line Fabry–Pérot cavity

Abstract

A polymer-based laser structure with an in-line Fabry–Pérot cavity has been invented using a self-written active waveguide. This device has a channel waveguide structure doped with organic dye and can be automatically interconnected with input/output waveguide ports. The most noteworthy feature, which may provide us with a promising technology for the integrated optical circuit, is that the device can be directly fabricated between passive waveguiding components. In optically pumped emission measurements, laser emission was output from the in-line Fabry–Pérot device via the interconnected optical fiber.
