Abstract
A study was conducted to demonstrate threshold behavior of laser modes in two different microring configurations under optical excitation. The first microring studied was formed by coating the conjugated polymer BEH-PPV on an etched fiber with a typical diameter of 50-100 μm and a polymer film thickness of <1-μm. The second ring resonator has a diameter of 35 μm and was formed by a Si3N4 ridge waveguide deposited on a SiO2 substrate. The samples were held in vacuum and excited under quasi-steady-state conditions using the second harmonic of a Q-switched Nd:YAG laser. The optical signals were detected by an optical multichannel analyzer with a spectral resolution >0.3 nm.
